Because Photoshop will launch successfully with a different OS X user account, can someone suggest which specific Console log(s) in both accounts to investigate (or search for the existence of) that may help diagnose why Photoshop won't launch?
In the problematic account, Photoshop starts to launch, and its menus appear. Many menus are black, but when you select a menu choice (such as Photoshop > About Photoshop or File > Open), then all Photoshop menus and choices gray out. Then you have to force quit Photoshop.
However, if you first (while menu choices are still black) choose File > Open in Bridge CS6 (or words to that effect), then Bridge will open.
There are numerous threads on promlems with Mavericks and PS, do a web search and see if any help you.. About the only thing I can offer I can offer is to reset prefernces. Start PS and immediately hold down option/command/shift keys. If fast enough you wlll get a reset window.
Thanks for the reply. Option-Command-Shift didn't help. I didn't get a reset window, or a splash screen. I finally gave up and migrated (200 GB) of data files to a new OS X account. We migrated only ~/Library/Preference items and ~/Library items for a minute number of programs (for example Mail.app and Contacts.app) and avoided moving any Adobe items from ~/Library and its enclosed folders.
