I work in Photoshop CS3, 10.01. (Didn't like the never versions I tried) Used to work on a MAC pro. NEVER any problems, sometimes PS would freeze and I would force quit, restart or shot down. When I do that new on my brand new iMAC the files that are open when I shut down get "damaged, truncated, or incomplete". Not only does it do that to the file that was open, it does it to the extra file that has the same name that I have save in another folder! I learned that my time machine hadn't been backing up today and I have lost soooooo much work!!! I am under deadline, I am desperate, PLEAEEEASE HELP ME!!!
