Has anyone else had issues with Mountain Lion preinstalled on their new Macs? I ran it since release on my Mac Pro flawlessly but since I have had this new iMac with it preinstalled I have had illustrator cs6 crashing on start up and also Corel Painter throwing out Error20 on start up. I never got any of these on my Mac Pro 2008 with Mountain Lion. The only solution is a clean install it seems since my two days of researching has yielded zero results.
