Hi there, I'm running a: iMac (27 inch, Mid 2010) Processor: 3.2 GHZ Intel Core i3 Memory 4GB 1333 MHz DDR3 OS X Yosemite 10.10.2 781GB Free of 999GB My issue is that my computer runs terribly slow. I am a designer and use inDesign CS6, Photoshop CS6, and Illustrator CS6 all the time. And it is crazy slow. It crashes all the time. No viruses, lots of spare room on the HD, but right now, the only things active are: Finder, Chrome, inDesign, Messenger and Stickies and I only have 449mb of free memory. Is my mac just too old? Have I destroyed it in some other way? Should I buy some RAM or a fancy new machine? Thanks for your help. Hope this isn't an annoying query.
