Hi mates, i'm having so much problems with mi mac pro 3.1 and PS. Every time i try to work with a large file (400MB) and put some layers, the PS freezes and i have to hard reset the mac. I try some different configurations and i get the same problems. I cannot work because every 10 mins or so i have to reset and lost some work. Can i upload some type of log errors? where can i find it? --- Post Merged, Nov 6, 2016 --- I'm thinking that could be my graphics card, a nvidia GTX 570, because in PS sometimes it's showing some artifacts and with a smaller files with no layers i have 0 problems with PS. There is some test that i could pass to the GTX? I have the last drivers and the graphic card is going well with all the rest OSX programs.
