Intel Mkl Library Mac

Intel® Math Kernel Library (Intel® MKL) helps you achieve maximum performance with a math computing library of highly optimized, extensively threaded routines. The library has C and Fortran interfaces for most routines. You can also find comprehensive support for several math operations including:

• Linear algebra
• Fast Fourier transforms (FFT)
• Vector math
• Direct and iterative sparse solvers
• Random number generators

Intel Math Kernel Library (MKL) Math.NET Numerics is designed such that performance-sensitive algorithms can be swapped with alternative implementations by the concept of providers. The routines in MKL are hand-optimized specifically for Intel processors. The library supports Intel processors and is available for Windows, Linux and macOS operating systems. The performance and efficiency of this library is impressive and has led to a dramatic reduction in. Intel Math Kernel Library (Intel MKL) is a library of optimized math routines for science, engineering, and financial applications. Wikipedia ( Intel MKL include BLAS, LAPACK, FFT,. The problem is being perfectly balanced between cores (embarrassingly parallel problem), so I suspect there is an issue with the MKL library on the linux workstation at home. Is there a way to verify that the MKL library is actually being used in python.

Step 1: Install Intel MKL

• From an application suite:

  Intel MKL installs as a part of these suites:

  • Intel® Parallel Studio XE (download from this page)

• From a repository:

  Download Intel MKL from one of these repositories.

• As a standalone package:

  Intel MKL is also provided as a standalone package under the Community Licensing Program.

Step 2: Select a function/routine

Select a function or routine from the Intel MKL library that is best suited for your problem. Use these resources:

The Developer Guide contains detailed information on several topics including: Compiling and linking applications Building custom DLLs Threading Memory management

The Developer Reference (in C and Fortran formats) contains detailed descriptions of the functions and interfaces for all library domains.

Use the LAPACK Function Finding Advisor to explore LAPACK routines that are useful for a particular problem. For example, if you specify an operation as: Routine type: Computational Computational problem: orthogonal factorization Matrix type: general Operation: perform QR factorization Additional property of the operation: factorize without pivoting The advisor displays the descriptions of several routines that match the requested operation. You can compare the results and select an appropriate routine for the operation.

Now I'm looking all over the place trying to find them. What is the default directory for the samples? I had meant to load the samples onto my dedicated drive for samples but did not get the. Also, unless you know how to network a PC and Mac together, you will need a Portable Hard Drive to make this happen. I used an 80GB Iomega drive that I’ve had forever you can get these very cheaply now. Here’s how to move your iTunes library from your Mac to your PC. STEP ONE: Open iTunes on your Mac. Go to iTunes Preferences.

Access Library Folder On Mac

The Library Folder on your Mac contains Preference Files, Caches, and Application Support Data.

While regular Mac users may not find the need to access the Hidden Library Folder, advanced Mac users will at times come across the need to access files inside the Library Folder for troubleshooting and other purposes.

One example of the need to access the Library Folder on Mac would be to rebuild the Database Files in the Library Folder, in order to fix Launchpad related issues like Apps Missing From Launchpad or deleted Apps showing up in the Launchpad.

Before going ahead with the steps to Access the Hidden Library Folder on your Mac, you need to be aware that ~/Library Folder contains important Data and Files related to Mac User Accounts.

Hence, make sure that you are accessing the Library Folder for a good reason and you do know as to what you are trying to achieve.

Access Hidden Library Menu Option On Mac

Follow the steps below to access the Hidden Library Menu option on your Mac.

1. Left-click your mouse anywhere on the screen of your Mac. This will reveal the Go Option in the top menu bar of your Mac. You can also click on the Finder Icon in the Dock of your Mac to activate the Go Option.

2. Next, click on the Go option in the top menu-bar of your Mac.

3. While you are still on the Go option, press and hold the Option key on your Mac and then click on the Library option that appears when you press down the Option Key.

Note: Press the Alt Key in case you are using a Windows keyboard with your Mac.

4. Clicking on the Library Menu option will take you straight to the Library Folder on your Mac.

Access Library Folder On Mac Using “Go to Folder” Option

Another way to access the Library Folder on your Mac is by using the Folder Option on your Mac.

1. Left-click your mouse anywhere on the screen of your Mac to reveal the Go Option in the top menu bar. You can also click on the Finder Icon in the Dock of your Mac to activate the Go option.

2. Next, click on the Go option from the top menu-bar on your Mac and then click on Go to Folder… option in the drop-down menu (See image below).

3. In the search window that appears, type ~/Library, and click on the Go button.

This will immediately take you to the Library Folder on your Mac.

Permanently Unhide the Library Menu Option On Mac

You can permanently unhide the Library Menu Option in the top-menu bar on your Mac by using the Terminal Command. The process is reversible and you can easily go back to the default hidden Library Menu Setting by using the Terminal command once again.

1. Click on the Finder icon in the dock of your Mac to activate the Go option in the top Menu bar of your Mac.

2. Next, click on the Go option in the top menu-bar and then click on the Utilities option in the drop-down menu.

3. On the Utilities window, open the Terminal App by clicking on it.

4. Next, type chflags nohidden ~/Library/ and Press the Enter key to submit your command for execution.

Is it possible to transfer iTunes library from mac to pc and/or pc to mac?

Many people have such puzzles, because iTunes is likely best known for its Mac associations, it’s quite likely that there are many households that only have their iTunes library on a Mac. If, however, a family member with a PC is heading off on a holiday and wants to bring their tunes or entertainment selection with them, it may be difficult to simply leave the copy of iTunes on one machine. It therefore makes sense to learn how to copy iTunes from a Mac to a PC to allow for greater portability for either system or either system’s music and entertainment files.

Part 2: Free Way to Transfer iTunes Library from Mac to PC

There are only a few steps involved with transferring your iTunes library from one computer to the other, and it does not matter, at least as far as iTunes is concerned, whether you are transferring from Mac to PC or the other way around. It is not a terribly complicated process, but it is one that must followed accurately in order to ensure the successful transfer of iTunes from your Mac to a PC.

Step 1. Open iTunes on your Mac

You need to open iTunes on your Mac in order to access your Preferences settings on your iTunes for Mac. Without working on your Preferences settings, you cannot successfully transfer iTunes from one computer to the next.

Step 2. Go to iTunes > Preferences

From here, you need to hit the Advanced settings in order to set the Mac to be able to transfer iTunes successfully over to your PC.

Step 3. Under Advanced in Preferences, click “Keep iTunes Media Folder Organized”

This will ensure that all your files are pointing in the right direction for your library, which ultimately makes the transference of your files easier. With an organized iTunes Media folder, your job in transferring iTunes from one system to the other becomes far less complicated.

Step 4. Click File > Library > Organize Library

This will help you to keep your songs organized in order to ensure they are in the same spot when you transfer them over to your new computer. You should also click “Consolidate Files” at this point as well; that will also help you by putting copies of all media files in the iTunes Media folder and keeping all original files in their original locations. This way all the files are pointing where they should to the locations on your drives and they should be accessible when you complete the transfer to the new computer.

Step 5. Plug your portable hard drive into your Mac

This gives you a hardwired location to which to transfer your iTunes from your Mac. On this new computer, try to take the time and put your iTunes files in the same location that you want to put it on the PC, more or less. Certainly, PC’s have a slightly different naming convention than for Mac. Confirm that there is a Music folder on your PC, and within that folder should be the iTunes folder. You can transfer the iTunes Library file and the iTunes Music folder from the portable drive to this folder.

Step 6. Change the name of the iTunes Library file

Because PC systems always need file extensions on them in order to be recognized and opened appropriately, you need to take the iTunes Library file that you just transferred from your Mac and change the name so that it has the right file extension. Right click on the iTunes Library file and rename it to iTunes Library.itl, and that should allow you to open every file that you had working in the Mac version of the program.

It should be noted that when you migrate iTunes from one computer to the other, the backups that you might have made of Mac handheld devices, such as iPhones, iPads and iPods, through iTunes will likely be lost. In addition, if you do not migrate your iTunes to the exact same location on the new PC, iTunes will not be able to find the media files, and then you might have a problem effectively using the program. So, take the time to migrate the files to the right location to ensure that you will be able to find them on the new PC.

At times, though, you may find it extremely helpful to transfer your iTunes library to an external hard drive simply in order to have a backup of your iTunes library. Having your iTunes library on an external hard drive also means that should you want to share that library with another computer or another person, you will be able to do so quite easily; if you have your external hard drive with you, it is simply a matter of taking the copy of iTunes and moving it you’re your portable hard drive to the system of your choice. Having a copy of iTunes on an external hard drive also gives you a certain degree of calm, as there have been multiple times where people have inadvertently lost everything on their computers, their iTunes files included. This can be incredibly distressing when it happens, and people want to be able to avoid this. It can sometimes take hours to build up an iTunes library, and this is time that many people do not always have.

Sometimes, people want to be prepared in the event they lose all the information on their computer, and an external hard drive can be a great tool to back up an entire hard drive on a laptop or on a desktop computer. This includes your iTunes library. Music and entertainment appear to be what make the world go round; after all, music is frequently used as a method of stress release, and we now live in a society where many expect to have a variety of forms of entertainment right at their fingertips. Having your entire iTunes library go missing on your computer can be distressing, but it does not have to be, as backing up the library to an external hard drive can prevent a great deal of stress.

Apple Mac Developer Library

The Library directories are where the system and your code store all of their related data and resources. In macOS, this directory can contain many different subdirectories, most of which are created automatically by the system. In iOS, the app installer creates only a few subdirectories in ~/Library (such as Caches and Preferences) and your app is responsible for creating all others.

Table A-1 lists some of the common subdirectories you might find in a Library directory in macOS along with the types of files that belong there. You should always use these directories for their intended purposes. For information about the directories your app should be using the most, see The Library Directory Stores App-Specific Files.

Table A-1 Subdirectories of the Library directory

Subdirectory	Directory contents
Application Support	Contains all app-specific data and support files. These are the files that your app creates and manages on behalf of the user and can include files that contain user data. By convention, all of these items should be put in a subdirectory whose name matches the bundle identifier of the app. For example, if your app is named MyApp and has the bundle identifier com.example.MyApp, you would put your app’s user-specific data files and resources in the ~/Library/Application Support/com.example.MyApp/ directory. Your app is responsible for creating this directory as needed. Resources required by the app to run must be placed inside the app bundle itself.
Assistants	Contains programs that assist users in configuration or other tasks.
Audio	Contains audio plug-ins, loops, and device drivers.
Autosave Information	Contains app-specific autosave data.
Caches	Contains cached data that can be regenerated as needed. Apps should never rely on the existence of cache files. Cache files should be placed in a directory whose name matches the bundle identifier of the app. By convention, apps should store cache files in a subdirectory whose name matches the bundle identifier of the app. For example, if your app is named MyApp and has the bundle identifier com.example.MyApp, you would put user-specific cache files in the ~/Library/Caches/com.example.MyApp/ directory.
ColorPickers	Contains resources for picking colors according to a certain model, such as the HLS (Hue Angle, Saturation, Lightness) picker or RGB picker.
ColorSync	Contains ColorSync profiles and scripts.

3. How To Clear Cache In Windows 10
4. How To Empty Cache On Macbook Pro

You’ve probably heard and seen the term 'cache' used on your Mac but do you know what it is?

Cache files are basically temporary data stored on your hard drive and used to speed up processes. For instance, Safari will download images on a webpage into cache so that next time you visit the site you don’t have to download the images again.

How are cache files different from cookies?

Cookie files are tiny members of the big cache family. This form of cache is collected by your browser to remember previously visited websites. Cookies collect the details of your visit, its duration, actions on a page, etc. Advertisers also use these to follow you around the internet. However annoying they are, cookies are a part of internet reality that we cannot help but “Accept.”

There are many reasons to remove old cache from your MacBook and disk space issue is only one of them. So what are the other benefits ?

Before going ahead with the steps to Access the Hidden Library Folder on your Mac, you need to be aware that /Library Folder contains important Data and Files related to Mac User Accounts. Hence, make sure that you are accessing the Library Folder for a good reason and you do know as to what you are trying to achieve. Clean up cache files manually. To find and clear your user cache manually, do the following: In your Mac’s user folder, there’s a hidden Library folder, which itself contains a folder of caches left by the applications you’ve installed on your Mac.

• Fixing issues with laggy web pages that load outdated content
• Removing personal data stored by websites and applications.
• You need to force-delete outdated cache from an app.

Are you ready to reclaim space on your Mac? Let’s go!

What are main cache types?

There are roughly three main types of caches you can clean on your Mac:

• System cache
• User cache (including app cache and DNS cache)
• Browser cache.

This article will go over cleaning up all three.

Now, when it comes to clearing cache on Mac, there are two ways you can do it. You can clean them up manually step-by-step, or you can clean them in second with a cleaning utility like CleanMyMac X. If you want to clear cache on your Mac right now, we suggest doing it the easy way:

Safari Cache Location

1. Launch CleanMyMac X (2019 version is preferable)
2. Select System Junk
3. Click 'Scan', and then “Clean”

That’s it, all cache files cleaned! CleanMyMac X works on all systems, including the latest macOS Catalina. You can download CleanMyMac X for free here and try.

However, if you’d like to clean them all manually, follow the steps below.

How to empty user cache on Mac?

Potential space reclaimed from junk - Up to 70%

As you can see, a single user cache folder on my computer takes up enormous 1.6 GB of space. And that’s just one folder out of hundreds. That means a good cleaning could free up gigabytes of free space and speed up your Mac in the process.

To clear your user cache, do the following:

1. Open a Finder window and select “Go to Folder” in the Go menu.
2. Type in ~/Library/Caches and hit enter to proceed to this folder.
3. Optional step: You can highlight and copy everything to a different folder just in case something goes wrong.
4. Go into each of the folders and clean out everything.
   Note: We recommend that you remove the insides of these folders, but not the folders themselves.

Now, repeat the same steps above, but substitute…
~/Library/Caches with… /Library/Caches

Make sure that once you have finished clearing out these caches for additional hard drive space, you empty out your Trash. To do this, Control-click on the Trash icon in the dock and select “Empty Trash.” Restart your Mac afterward so your Mac can begin to create new, fresh cache files.
To help you make sense of your Library folder here's a brief explanation what each sub folder stands for.

4 main types of cache within Library folder

Caches
Temporary data created by apps and websites. Your apps keep generating cache files for as long as they are active. Relying on such pre-loaded content reduces memory load and speeds up data exchange.
Preferences
Prererences folder is where you’ll find customized settings for your apps. Sometimes, there is a need to reset an app and delete its corrupted Preferences file. Preference files always end with .plist — so they are easy to spot and delete.

App support
App support folder contains large pieces of app data, like game saves. App support files may remain on your Mac long after you’ve deleted the app itself. That’s why “cleaners” for system junk were invented.

Containers
Containers folder is an exchange buffer that apps use to communicate with one another. This is often referred to as “sandboxing.” Containers folder is automatically emptied after you restart your Mac.

If you aren’t comfortable with the risk of deleting user cache manually, a specialist cleaning app CleanMyMac X can do it for you. It will only remove files you don’t need and will find up to 7x more temporary cache files to remove from all over your system.

How to delete system and app cache on Mac

Potential space reclaimed from junk - Up to 10% (manual methods) or 15% (using cleaner)

Next up we’re looking at your system cache files. These hidden cache files are mainly created by the apps that run on your Mac.

What is app cache? In short, it’s any media downloaded by the apps you use in order to work faster and not load it every time you open the app. Do you need it? It’s debatable, but app cache takes up disk space and can be cleaned.

You can delete app cache on Mac in the same way as user cache, by going to ~/Library/Caches and removing the insides of the folders with the app name.

Open Hidden Library In Mac

Proceed with caution! Not all app cache can be safely cleared. Some app developers keep important user info on cache folders. Backing up a folder before you delete is always a good idea. If everything works fine then you can delete the backup later.

To be on the safe side, use CleanMyMac, it works with a Safety Database and knows how to clear app cache safely. As if that wasn’t enough it will also remove more junk than manual methods.

How cache is created? An example from Photos

Every time you do image manipulations, like rotating a picture, its additional copy is created on your drive. In this manner, just 4 rotations are enough for an image size to grow from 2.5 MB to 10 MB of disk space taken. If you edit photos and videos on a regular basis, you may notice that your editor application also keeps temporary data — like intermediate version of your files.

How to clear browser cache on Mac

Potential space reclaimed from junk - Up to 15%

We all love to surf the web but every site we visit adds to the growing browser cache. Clearing your browser cache doesn’t just free up space, it will can also clear your browsing history to secure your privacy.

Browser cache temporarily stores website data such as images, scripts, and other stuff, in order to make your browsing faster when you revisit the same site. If you’re worried about your privacy or want to hide pages you’ve visited, you can clear your Internet cache (or browser history). Also, resetting your browser cache will potentially help to get rid of 404, 502, and other errors caused by corrupted cache.

Each browser has its own cache location, so the process of clearing is different in each case. For instance, Chrome cache location is in Settings, Safari stores its cache in Privacy, and Firefox cache location is History tab.

Here’s a quick introduction into how to delete browser cache on Mac.

How to clear cache in Chrome

Here’s how to clear browser cache in Chrome manually:

1. Click the 3-dot icon in the top right corner of Google Chrome browser.
2. Choose Settings.
3. At the bottom of the menu, choose Advanced.
4. Click “Clear browsing data.”
5. Deselect all, but Cached images and files.
6. Timewise, choose All time.
7. Hit “Clear data” button.

How to clear cache in Firefox

Here’s how to delete cache in Firefox manually:

1. Click the hamburger icon in the top right corner.
2. Choose Privacy & Security on the left sidebar.
3. Scroll to the section 'Cached web content' menu item.
4. Now, click Clear Now to delete Firefox cache.
5. Exit/quit all browser windows and re-open the browser.

In the same menu, checkmark Override automatic cache management and limit the cache size in MB. Go with the default amount of 350 MB, which is enough for most users' needs.

TIP:

If for some reason you cannot open a web page, try putting cache: in front of the URL address. This redirects you to the site’s cached copy.

For example: cache:macpaw.com

It works most of the time and can magically open even the otherwise blocked sites.

How to clear cache in Safari

Safari is a little trickier than the rest of the browsers. You could remove caches together with all the other website history through History — Clear History in menu bar.

But if you need more precision, here’s how to empty cache on Safari browser:

1. In the top menu, choose Safari.
2. Click Preferences.
3. Choose the Advanced tab.
4. Enable Show Develop menu in menu bar.
5. Now go to Develop in menu bar.
6. Choose Empty caches.

Make sure you close/quit the browser and restart it after clearing cache. Note, that all your auto logins and predicted websites in the address bar will be cleared.

Manual methods remove most of the browser junk but if you want to remove all of it, from all your browsers at once, there’s a safer and faster method to clear your internet cache on any browser.

How to clear cache files on Mac with a single click of a button

Instead of searching all over your Mac to find and remove cache files yourself, you can clear user caches on a Mac using CleanMyMac X. It makes removing cache files as easy as can be.

To get rid of cache files with CleanMyMac X:

1. Download CleanMyMac X (free) and launch it.
2. Select Smart Scan in the left menu.
3. Hit Scan at the bottom of CleanMyMac X.
4. Then click Clean.

And you're done! If you’d like to remove only cache files and nothing else, click on Review Details before clicking Clean. Deselect everything but System Cache Files and User Cache Files, then click Clean.

The easy way to clear all browsing data

Instead of clicking between browsers and being limited to what they let you clean, take full control of all your browser cleaning with this simple method:

1. Open CleanMyMac and select the Privacy module
2. Click on your browser of choice
3. Make your selections from the list of all your cache and privacy tracks
4. Click Remove to clean your browser

Cleaning your Mac has never been easier. Download CleanMyMac X and try for free to get yourself a faster, cleaner Mac — without worrying about cleaning the wrong thing.

Apple's iCloud Photo Library service works seamlessly to sync and back up your images and video across all of your Apple devices to iCloud — but if you're serious about keeping your irreplaceable photos and video safe, you'll want a redundant (second) backup. Because as they always say, you can never have too many backups! And it's better to be safe than sorry, honestly.

Backing up your photos can take the form of a local backup on your own drive or an external source, a secondary online backup, or both. Here's how to do it all.

How to back up iCloud Photo Library to your Mac's hard drive

The best way to back up the images and video in iCloud Photo Library is to make sure you're downloading all your content onto your Mac.

Note: If you plan to back up your entire digital library to your Mac's hard drive, you'll likely want to do it on a desktop Mac with a 1TB drive or higher. Otherwise, consider backing up to an external drive.

1. Launch the Photos app on your Mac.

5. Click Download Originals to this Mac.

Your Mac will now download full-resolution copies of all your images to your Mac's hard drive, stored inside your Photos app library.

How to back up your iCloud Photo Library content to an external drive

There are two ways to back up your iCloud Photo Library to an external drive: by backing up your Photos library automatically, or manually. (You can also export sections of your library if you don't want to back up the whole thing.)

Back up your Photos library automatically

If you've turned on the Download Originals option for your Photos library, you can back up your Photos library as part of your regular backup routine. Whether you use Time Machine or clone your hard drive using SuperDuper! or Carbon Copy, your Photos library (and all images and video automatically downloaded from iCloud) will be backed up as well. (And if you don't currently use a backup service, well... now's a good time to start!)

Back up your Photos library manually

If you've turned on the Download Originals option for your Photos library but don't want to back it up automatically, you can always copy your Photos library to an external drive at regular intervals.

1. Connect an external drive to your Mac via USB, USB-C, or Thunderbolt.

2. Open a new Finder window on your Mac.

How to make an online backup of your iCloud Photo Library

Even though your entire iCloud Photo Library is (as the name implies) stored online in iCloud, it's worth considering a second online backup as one of your redundancies.

If you store your entire iCloud Photo Library on your Mac

Good news: If you already use a service to back up your hard drive and you've synced your full iCloud Photo Library to your Mac, it's easy to back it all up. (If not, consider it a good time to start!)

If you don't store your iCloud Photo Library on your Mac

If you don't store your iCloud images locally, this is a bit trickier: you can use the external drive method to export portions of your library to an external drive, then sync that drive to your preferred online backup service, but it's a bit more labor-intensive. In general, this is why I tend to recommend backing up your full library to your Mac or storing a library on an external drive.

Open Library In Mac

To combine Photos libraries, open the source library and export the photos and videos that you want to keep. Then open the destination library (the one that you want to use as your main library) and import the photos and videos.

Ever since Lion (OS X 10.7), Apple has hidden your personal Library folder (/Library) by default. In Lion and Mountain Lion (OS X 10.8), you could make the folder visible, but it required some work. Dec 12, 2016  The User Library folder is hidden by default in MacOS Catalina, MacOS Mojave, macOS High Sierra, and macOS Sierra, but some advanced users may wish to show and access the /Library/ folder, which contains preference files, caches, and application support data. Apr 21, 2015  I successfully migrated from iPhoto library to this new Photos Library in April.17th, and everything seems okay except for some minor bugs. But from yesterday on, I started Photos and got this message 'Can't open Photos Library, try another.' If I try reading iPhoto or Aperture Library. Some troubleshooting procedures require you to navigate to and view a hidden folder on Mac. You can access the Library folder with the Go To Folder command or from the Terminal app. Access the Library folder in Finder: In Finder, choose Go Go To Folder In the Go To The Folder field, enter /library/ Click Go. Enter 'open library'.

Choose a photo library

Here's how to open one of the multiple photo libraries that you might have on your Mac or on a connected external drive:

1. Press and hold the Option key as you open the Photos app.
2. Select the library that you want to open, then click Choose Library.

Photos uses this library until you open a different one using the same steps.

Export photos and videos from the source library

Open the source library, then decide whether you want to export your files as unmodified originals or edited versions:

Edited versions retain their edits when you import them. The advantage is that you don't have to recreate any edits; however, these files become the destination library's originals. This means that you can't revert to their earliest pre-import version.

Unmodified originals don't show any edits that you made when they were in the source library. This gives you flexibility for later editing, but recreating your edits might take substantial work.

How to export edited versions

1. In the Photos app, select the photos and videos that you want to export. To select multiple items, press and hold the Command key while you click. To select a group of items in order, click the first one, then press and hold the Shift key while you click the last one. This selects all of the items between the two that you clicked.
2. Choose File > Export > Export [number].
   
3. An export dialog appears.
   
   • In the Photos section, set Photo Kind to JPEG, TIFF, or PNG. JPEG recompresses your photos, which may result in smaller file sizes. TIFF and PNG files are higher fidelity and may result in larger file sizes.
   • In the Videos section, choose a Movie Quality setting. This section appears only if your selected items include videos.
   • In the Info section, select the checkboxes if you want to preserve metadata and location data in the exported files.
   • In the File Naming section, set File Name to Use File Name and set Subfolder Format to either Moment Name or None. Moment Name creates a subfolder for each Moment that's represented in your selected items. This is useful if you'd like to create an Album in the destination library for each Moment. The None option exports all of the files directly into the destination folder.
     
4. Click Export. A Finder dialog appears.
   
5. Navigate to the location where you want to save the files, such as the Desktop or an external drive. Click New Folder if you create a new folder for your exported items.
6. Click Export.

How to export unmodified originals

1. In the Photos app, then select the photos and videos that you want to export. To select multiple items, press and hold the Command key while you click. To select a group of items in order, click the first one, then press and hold the Shift key while you click the last one. This selects all of the items between the two that you clicked.
2. Choose File > Export > Export Unmodified Original.
   
3. An export dialog appears.
   
   • If your photos include IPTC metadata (such as titles or keywords) that you want to keep, select the Export IPTC as XMP checkbox.
   • Leave the File Name setting on Use File Name.
   • Next to Subfolder Format, choose Moment Name or None. Moment Name creates a subfolder for each Moment that's represented in your selected items. This is useful if you'd like to create an Album in the destination library for each Moment. The None option exports all of the files directly into the destination folder.
     
4. Click Export. A Finder dialog appears.
   
5. Navigate to the location where you want to save the files, such as the Desktop or an external drive. Click New Folder if you create a new folder for your exported items.
6. Click Export Originals.

How to import photos and videos into the destination library

Open the destination library, then drag the folder that contains your exported items into the main area that shows your other photos and videos. When a green plus sign appears on your pointer, you can release the folder.

The photos in the folder are sorted into Moments based on their creation dates and locations. The videos are sorted based on the date you exported them from the source library.

If you created subfolders when you exported the items and you want to create an Album for each subfolder, follow these steps:

1. In the Finder, open a subfolder.
2. Select all of the photos and videos within the subfolder.
3. Drag the items onto My Albums in the Photos sidebar.
4. Name the Album in the highlighted text box that appears in the sidebar.
   
5. Repeat for each subfolder.

Save space by deleting the source library

If you're sure that you've exported all of the photos and videos that you want to keep from the source library, you can delete it to save disk space on your Mac.

First, open the Finder and find the source library that you want to delete. By default, photo libraries are stored in your Pictures folder. If you can't find the library, follow the steps to choose a library; the path to the selected library's location appears in the Choose Library window.

Next, move the source library to the Trash. Then choose Finder > Empty Trash to permanently delete the files.

Back up your library

Before following any of these steps, it's a good idea to create a backup of your photo library, even if you use iCloud Photos. You can use Time Machine, use a third-party backup solution, or copy the library to an external drive. By default, your photo library is stored in the Pictures folder within your home folder.

Make sure that your software is up to date

Photos is part of the Mac operating system. You can avoid or fix many issues by running the most up-to-date version of macOS. Learn more about updating the software on your Mac.

If the Media Browser isn't showing your photos and videos

Open Library Folder In Time Machine

Use the Media Browser to make images from your photo library available in other apps, like Pages and iMovie. The Media Browser shows only the contents of the Photos library designated as the System Photo Library. If you have more than one Photos library—and the one you're using isn't set as the System Photo Library—the Media Browser won't show its contents.

Open Library Mac Mojave

Follow these steps to designate the current library as the System Photo Library:

1. Choose Photos > Preferences.
2. Click the General button at the top of the Preferences window.
3. Click Use as System Photo Library.

Open Library In Finder Mac

If you're having other issues with Photos

If you're experiencing other issues—like missing or blank photo thumbnails, unexpected behavior, or if Photos won’t open—try to see if it's an issue with your library by following these steps.

Create a new Photos library and see if your issues persist:

1. Quit Photos.
2. Press and hold the Option key while you open Photos.
3. In the dialog that appears, click Create New.
4. Give your new library a name, then click OK. Note whether Photos opens successfully with this new library.

To return to your main Photos library, quit Photos. Then open it again while holding the Option key, select your main library, and click Choose Library.

Alternatively, you can open Photos in another user account on your Mac and note whether Photos opens successfully.

If Photos opens with the new library, or in a different user account, it might mean that there's an issue with your library. Follow the steps to use the Photos library repair tool on your main Photos library.
