My Photoshop CS6 extended for Mac, was working fine, then there was a power failure, after that it crashes immediately when I try to launch the program. I can't open the app at all. Tech support wont help me, becuase CS6 support reached end of life, said to post here.
Try holding down Cmd+Opt+Shift as you start Photoshop. The timing is a bit tricky but you should get a dialogue asking if you want to delete the Photoshop Settings file. Do that and it will build a new one on starting.
Dave, It didn't work, one time for a half second I think it shwoed a dialog about deleting the settings, but then crashed immediately before I could click it. After that it just crashes immediately, don't even get to see that. Are there some files in the Library I can delete (Preferences, Application support, etc) that will accomplish the same thing?
