[QUOTE="Rod, post: 1911975, member: 204485"] We seem to hear about this issue quite frequently with early model Mac's, they work perfectly when they are working then for no apparent reason shut down. Other users have found the same results from testing all of the obvious causes, battery, background apps, peripherals, overheating with no apparent cause. I personally had this problem with a 13" 2015 MBP which I managed to keep under control using a utility called Amphetamine which prevents the CPU from sleeping during times of inactivity but that doesnt seem to be a universal remedy. To eliminate any software issue one really needs to erase the HD and install a fresh copy of the Operating System and user preferences from scratch. Maybe you have already done that. That would leave harder to check items like the power circuit. None of which is much help I'm afraid. [/QUOTE]
