Imported the wrong iPhoto library into Photos. Can I start over?
Not only did I accidentally import the wrong iPhoto library, but when Photos set itself up, it ended up on one of my external drives rather than the internal drive of my computer. (That may be because that particular drive USED to be the internal drive of my PREVIOUS computer.)
Anyway, how do I go back to square one with Photos and make sure it ends up on my internal drive?
Incidentally, IS there a Photos forum? I didn't see one. That's why I'm posting my question here.
MacBook Pro, OS X Yosemite (10.10.3), 2.5 Ghz Intel Core i5
