Since I went from CS6 to the creative cloud, I have been having problems with Adobe applications (specifically PS and LR). I have contacted Adobe, but have yet to receive a response. After PS loads, as soon as I click within the screen, I get the beach ball which lasts from 2-4 minutes, then the program seems to run fine. In LR, I get the beach ball, and am now having trouble synchronizing folders. The program freezes on imports. I am running on a quad core 5 year old(isn) MacPro, 32 Gigs RAM, nVidia graphics card, external port multiplier SATA Mercury xPro2 drives. Haven't a clue, but am concerned about a 50,000 image LR library with numerous edits. I have taken all of the usual steps, permission repairs, have used an Adobe recommended clean up program. I'm fresh out of ideas. Any thoughts?
