Mavericks will not open iphoto library upgrader
I just downloaded OS X 10.9 Mavericks, and now I can't open iphoto 9.5 . I have to download the iphoto library upgrader, but when I do, it will not install. I am directed to move upgrader to the trash, as it may be damaged or corrupted. Where to turn to??? Operating MacMini OS X 10.9.
Mac mini, OS X Mavericks (10.9)
