Get rid of migrated iPhoto Library
Since I switched to Photos in 2015, I am still keeping iPhoto Library.migratedlibrary - just in case.
Today, in Monterey, I tried whether Photos could live without it, so I moved it to another place.
But then Photos didn't start. So I moved it back, and Photos came alive again.
Does anyone how to get Photos to work without the old migrated library?
All my images are already in the Photos Library, and I didn't use iPhoto for years.
Thanks for any clue!
