Dec 13, 2018 Map a network drive on Mac. Once OS X finds a network drive, you will be able to connect to it and access the resources you have permission to access. We can configure OS X to automatically mount the drive in the future to save having to do this every time you want to access something. Mounting is the technical term for opening the drive to use it. To do it, go to the Finder on your Mac and choose Go iCloud Drive to open an iCloud Drive window, and then drag the movie into the window. Alternatively, you can expand Photos’ Export pane.
Prepare your drive
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.
Move your Photos library to an external storage device
- Quit Photos.
- In the Finder, go to the external drive where you want to store your library.
- In another Finder window, find your library. The default location is Users > [username] > Pictures, and it's named Photos Library.
- Drag your library to its new location on the external drive. If you see an error, select your external drive's icon in the Finder, then choose File > Get Info. If the information under Sharing & Permissions isn't visible, click , then make sure the 'Ignore ownership on this volume' checkbox is selected. If it's not selected, click to unlock it, enter an administrator name and password, then select the checkbox.2
- After the move is finished, double-click Photos Library in its new location to open it.
- If you use iCloud Photo Library, designate this library as the System Photo Library.
Delete original library to save space
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.
Open another Photos library

If you have multiple libraries, here's how to open a different one:
- Quit Photos.
- Press and hold the Option key while you open Photos.
- Select the library that you want to open, then click Choose Library.
Photos uses this library until you open a different one.

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.
I want to send about 500 photos (2 GB) from my iMac to a removable flash drive, for sharing with a friend who uses Windows. I use iPhoto. I created an album and put it in a folder by using File>new folder>drag&drop. How do I transfer the folder to a flash drive in a USB socket? (I was able to burn to 3 CDs by splitting the file into 3 smaller files of about 650 MB each, but they can't be read on a Windows computer).
Are all my photos 'locked in' to the iPhoto library?
This seems like it should have an obvious, simple solution. Any help would be appreciated.
