    Photoshop CS6 freezing on Mac OS 10.6.8


      Hi one of our Macs (OS 10.6.8) is freezing when we try using Marquee Selection or Feathering or Cut and Pasting in a PSD file using Photoshop CS6. Basically we have to hard reboot the Mac as we get no error message, just a locked up computer. All the other Macs are exactly the same but don't have this issue.


      The file has no fonts in it, it is just an image with Layers that have no Effects. File size is 900MB.


      All updates for both CS6 and Mac OS have been run and all is up to date.


      Please advise.

          it would probably help to note which Mac you have, ram, video card, additional plugins, font situation, system haxies, drawing tablets, working off network disks, ect...


          if you ran Disk Utility> Repair Disk, Repair Permissions, and a maintenance utility like Cocktail OSX to clear out the caches (especially fonts)


          after that, try a New User account to rule out user preferences


          we have to hard reboot the Mac as we get no error message, just a locked up computer.



          that may be a clue to someone else but it sounds like you have some work to do ruling out hardware if the above doesn't help (and the install is otherwise ruled out)

            Here are the base specs (serial info deleted). We're running the file off the hard drive and there are no additonal plugins. We use a standard font library but as I said, file has no text/fonts in it. It's completely locking up while using the marquee selection tool.


            Cleared user preferences too when starting PS.


            Gonna try a fresh reinstall and see if that fixes it, if it doesn't I think there is something wrong with the Mac itself because we have 6 more identical machines and they are not having this issue.

              If the whole machine locks up, you have 3 possibilities: bug in the OS, bug in a low level driver, or defective hardware.


              Bad RAM, bad VRAM, and bad GPUs are the most common causes.
