Your Photos library holds all your photos, albums, slideshows, and print projects. If your library is large, and you want to free up storage space on your Mac, turn on iCloud Photo Library and use Optimize Mac Storage, or move your library to an external drive.
Before you start, be sure to back up your library.

You can store your library on an external storage device, such as a USB or Thunderbolt drive formatted as APFS or Mac OS Extended (Journaled).1 Find out how to check the format of your external storage device.
To prevent data loss, Apple doesn't recommend storing photo libraries on external storage devices like SD cards and USB flash drives, or drives that are shared on a network.
After you open your library from its new location and make sure that it works as expected, you can delete the library from its original location.
In a Finder window, go back to your Pictures folder (or whichever folder you copied your library from) and move Photos Library to the trash. Then choose Finder > Empty Trash to delete the library and reclaim disk space.

If you have a permissions issue with your library, you might be able to resolve the issue by using the Photos library repair tool.
1. You can't move your library to a disk that's used for Time Machine backups.
2. If the volume isn't formatted APFS or Mac OS Extended (Journaled), or has been used for Time Machine backups but hasn't been erased, this checkbox will either not be present, or won't be selectable after unlocking. Erase and reformat the drive for this option to be available.
When you import photos and videos into Photos, they’re copied to the Photos library in the Pictures folder. If you prefer, you can store photos and videos outside the Photos library (for example, in a folder on your Mac or on an external drive) and still view them in Photos. Files stored outside your library are called referenced files.
Referenced files aren’t automatically uploaded and stored in iCloud, and they aren’t backed up along with the rest of your files when you back up your photo library—you must back them up manually. To avoid manually backing up referenced files, you can move or consolidate the files into your library.
In the Photos app on your Mac, choose Photos > Preferences, then click General.
Deselect the “Copy items to the Photos library” checkbox. Kontakt library mac download mac.
