After upgrading to the latest OSX, I am unable to open my dinosaur version of Photoshop (CS5.1). Getting a "Could not complete your request because of a program error" message. (how would I see my logs about this?) Just wanting to report this - even though I know I am WAY overdue for a Photoshop upgrade - just in case someone else is having the same problem, and if there's a fix without shelling out $. Thanks.
