Got a new iMac and want to bring in some very old photos.
My old photos were backed up on a Seagate hard drive. Photos won't allow me to import the library that was stored. It says The library “Photos Library” is in a TimeMachine backup. Open the original library. The original library is on another machine I no longer have. How do I get my old photos back?
iMac 24″, macOS 11.4
