Photoshop CS5 suddenly slow.
Never seen this before. My 8 core 2.8 GHz Mac Pro has 10 GB RAM and a blank 100 GB scratch disk. Photoshop is always quick. Has been for years. Suddenly today, Photoshop is slow like molasses to open & save files. Lots of progress bars and wait cursors. Everything else on the Mac is fine. It boots quickly & normally, and other apps are happy. My boot drive, a clean installed Mountain Lion system, says S.M.A.R.T. Status: Verified. In Activity Monitor, a process with ID # 0, Kernel Task, was using 700 to 800 MB RAM, while another process, mds, with ID # 44, is using 350 MB RAM. Does anybody know what is going on?
I should add that I booted from a backup system and its copy of Photoshop was also doing the same thing. In addition, a high level troubleshooter on Apple Discussions informed me that my present level of 500 MB RAM for Kernel Task is normal. So all I know is Photoshop is suddenly slow.
