Migrating old iPhoto library to Photos?
I have a MacBook Pro 2021 (running Sonoma 14.3). I have been going through my external harddrives to recover old photos, and I have found a few backups of old iPhoto libraries.
When I click them, I get a popup stating that "The library (...) is not supported and it can be opened with macOS Monterey (version 12) or earlier. Alternatively you can use Library import add photos from one library to another."
As stated, I have macOS 14.3, so I cannot open with Monterey. When I try to import them in Photos, they're greyed out, so that is not an option either.
What to do, hope someone out there can help me.
MacBook Pro 15″, macOS 10.12
