Migration Assistant copies all of your files from your old Mac to your new Mac so that you don't have to copy them manually.
Iphoto Migrated Library
- If your files are currently on a PC, follow the PC migration steps instead.
- If you're moving content from a Time Machine backup, follow the steps to restore your Mac from a backup instead.
- Just a quick question about the iphoto migrated photo library. After migrating the library to photos when Sierra released, I have the migrated iphoto library listing its size as 153 GB and the new photos library as 162 GB. Google searches have been a bit unclear.
- Removing the iPhoto Library package can help to free up disk space in some situations (but not always, more on that in a moment) but before doing this you need to be absolutely 100% certain that your pictures, photos, and videos have successfully migrated over to the Photos app and stored in the new photos library, that you have a fresh backup.
After you migrate your iPhoto or Aperture library to Photos, you might feel tempted to delete your original iPhoto or Aperture library. Because the migrated library takes little additional space, you don't need to delete the original library. So don't do it, even if you're tempted to. You can still use your original photo library with iPhoto.
Get ready
- Install all available software updates on both computers. If your old Mac isn't using OS X Lion or later, and your new Mac isn't using OS X Mavericks or later, follow the Mountain Lion migration steps instead.
- If both computers are using macOS Sierra or later, place them near each other with Wi-Fi turned on. If either one is using OS X El Capitan or earlier, make sure that both are on the same network.
- On your old Mac, choose Apple menu > System Preferences, then click Sharing. Make sure that a name appears in the Computer Name field.

On your new Mac
- Select the information to transfer.
In this example, John Appleseed is a macOS user account. If it has the same name as an account already on your new Mac, you're prompted to either rename the old account or replace the one on your new Mac. If you rename, the old account will appear as a separate user on your new Mac, with a separate home folder and login. If you replace, the old account will delete and then replace the account on your new Mac, including everything in its home folder. - Click Continue to start the transfer. Large transfers might need several hours to complete.
- After Migration Assistant is done, log in to the migrated account on your new Mac to see its files.
