How do I fix this problem on my early 2009 iMac OS X 10.5.6: “This operation could not be completed (com.apple.installer.pagecontroller error -1.) I had this happen when I wanted to open the .psk file to update my mac to mac os x yosemite. I downloaded it from the apple website, so safety is not an issue. I hope someone can fix it =) I’ll pay you a beer, haha.
Got a tip for us?
