How To Move Photos To External Hard Drive Mac

Select Photos to Transfer. Go to “iPhone LIBRARY Photos”. Your iPhone pictures will display in the right side of the window. Select the photos that you want to transfer to external hard drive Mac by tapping “Transfer” button at the right bottom of the interface. How to backup Mac photos to an external hard drive In theory, manually dragging and dropping your pictures to an external hard drive is a way of backing them up. But if you’d prefer something a little more automatic, then you should use the built-in macOS feature, Time Machine.

Photos are some of the most important files people want to keep safe. Storing them in the cloud is nice, but you might also want the peace of mind of having your pictures stored locally. Luckily, it’s easy enough to copy your Mac’s Photos library to an external drive.

This guide assumes you’re using the actual “Photos” app on your Mac, the default if you’ve used iCloud Photo Stream or imported from your iPhone. If you just have your photos in a folder on your Mac, all you need to do is plug your external drive in and move them over. If you’re using another app that maintains a library, you’ll have to configure things within that app.

Moving Your Photos Library

To understand how this works, it’s important to know how the Photos app catalogs files. It’s actually simple; there’s a single file that contains your entire library. If you want to back this up, you plug in your external hard drive and drag the whole file over to that hard drive in the sidebar of Finder.

The harder part comes when you need to change which Photos library you want to use. You’ll have to change the location from which the Photos app is reading.

In the image below, I’ve got two Photos libraries, the default one, and a backup library.

While you can access the backup library just by double-clicking it—which will open it in the Photos app—it’s better to switch Photos to use this one by default. You can always switch back to the regular library when you need to.

Double click the backup library to open it, then open the preferences for Photos from Photos > Preferences in the menubar.

Select “Use as System Photos Library,” which will change the default to the new library.

Back Up Your Drive Automatically With Time Machine

Backing up files manually is not the best solution, as you can never predict when your computer will break. It’s better to back up automatically, so you don’t have to think about it at all. Apple’s built-in Time Machine is the best tool for backing up to an external drive. You can read our guide on setting it up to get started.

Steps to Move your Photos Library to an External Drive

  1. Attach your external hard drive to your Mac.

  3. Open a Finder window and verify that your new storage device is correctly attached. You should see it listed under Locations in the Finder Window.
  4. From the left panel in the Finder window, select Pictures. If Pictures is not an option, go into Finder’sPreferences> Sidebar and check the box Pictures.
  5. Right click on the Photos library icon and select Get Info. Verify that you have enough free space for the library on the external drive.
  6. Drag and drop the Photos library icon onto the hard drive icon either in Finder or on your Desktop.
  7. Wait for the copy to complete. The elapsed time will vary based on the size of your library.
  8. When finished copying, hold down the option key while launching the Photos app.
  9. Click Other Library and navigate to the new location on the external device.
  10. In the Photos app, click on Preferences> General and select ‘Use as System Photo Library’. This is mandatory if you use iCLoud with your Photo library.
  11. Go to System Preferences> iCloud > Photos > Options. Select iCloud Photo Library to turn iCloud back on for your Photos.
  12. Disconnect your external hard drive and verify that all of your photos are indeed in the Photo library on the device. Once you are certain that the process is completed, you can drag the Photo library on your Mac to the Trash.
  13. If you want to immediately free up hard disk space, empty your Trash to permanently delete the photos.
