Hi Gary, I am using an older Mac with “only” 80 gig hard drive. Operating system is 10.11.6. When the conversion from iPhoto happened, my pictures took over my computer and I now have less than 1 gig left. I preferred the old way of transfer using a physical connection to Image Capture to transfer to an external drive. Now with iCloud, I can’t do that. Neither can I download from the cloud anywhere but my hard drive (which doesn’t have room). I’m afraid of losing data but something must be done. Is there a solution? I realize that performance will be slower but I need the computer for other things as well. I’m really afraid to take ANY step until I’m certain I won’t delete data. I looked through your posts, questions and answers and I didn’t see this specifically addressed. If I’ve missed it, please feel free to direct me to that conversation. Many thanks.

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.

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

1. Quit Photos.
2. In the Finder, go to the external drive where you want to store your library.
3. In another Finder window, find your library. The default location is Users > [username] > Pictures, and it's named Photos Library.
4. 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
   
   
5. After the move is finished, double-click Photos Library in its new location to open it.
6. 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:

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