I have a 2013 3.7 GHzMac Pro Updated OS X to Sierra when it came out. It recently started freezing and subsequently crashing when opening Adobe CC as well as iTunes. Will reboot fine but then when the application reopens on start up, it starts the cycle again. I've tried reseating the RAM to make sure it wasn't an issue. Tried a clean install of Sierra. Booting in safe mode allows me to open iTunes. Ran Disk Utility verify/repair disk with no errors found. Ran the hardware check with no issues found. Tried restoring to Mavericks, which it came with and I don't seem to have the same problem. I went ahead and ran an install of El Capitan and the problem is back. Found that previous shutdown cause -62 unresponsive application. Here's the Log File I have in Console: Core: 0 IA32_MC20_STATUS=0xFE200000000C110A IA32_MC20_CTL=0x0 IA32_MC20_ADDR=0xA0701440 IA32_MC20_MISC=0xDCFC381606802086 Core: 6 7 IA32_MC3_STATUS=0xBE00000000800400 IA32_MC3_CTL=0x0 IA32_MC3_ADDR=0x3F7F8D13FD16 IA32_MC3_MISC=0x3FFFF I've searched threads and the google to no avail. Any Help would be greatly appreciated.
