Setting up a new Mac mini - migrating photos from an external drive
All the data used in Photos on my current Mac are on an external drive. (No photos except old iPhoto images are on the old iMac.) How do I ensure that the photos on the external drive are migrated to the new Mac mini and directly usable by Photos? I’m concerned that if I just do a straight “automatic” migration the new mini will replicate how the old iMac handled Photos (i.e. without any photos stored on the computer) and won’t pull in the data from the external drive. On the advice of an Apple specialist online some years ago, we moved all the photos to an external drive because there were permissions issues between accounts on the old iMac. We’d like to go back to having Photos store all the photos on the computer, with only backups on external drives. Any advice?
