I just upgraded to OSXYosemite on my Mac and then tried to use my Photo Shop. It said to download JavaForOSX2014-001-dmg...so I did. Then I attempted to open PS again and an error message came up which said, "an unexpected and unrecoverable problem has occurred. Photoshop will now exit. What should I do?
Which version of photoshop?
You'll probably need to reinstall photoshop and then apply any needed updates.
