Just got a new Mac Smoke. It's Autodesk Smoke 2013 on a new iMac with 32G ram and fastest processor that you can get on it. When I have Smoke open and it sits idle for 3-5 minutes and try to use Smoke again I get the Mac spinning wheel for 10 seconds every time. I have the Mac settings as Autodesk recommends. Not sure what to do next.
