Hey everyone, Turning to MR for help here as I am at a loss as what to do with this situation. This resulted from the iPhoto to Photos update last year. As can be seen in the screenshot, I have three libraries, all about the same size according to Finder (but not the same according to Daisy Disk). My Photos.app claims Photos Library 2 is my library, but I do not understand why I still have an iPhoto library, and a normal Photos Library, also do not know why there is a Photos Library 2 to begin with. I didn't have issues updating to Photos.app or updated twice or anything like that. Trying to save some space on my HD, anyone with this setup who upgraded from iPhoto know which directories I can safely delete? Do not want to corrupt anything... Thanks all!
