And what the rated maximum operating temperature of the iMac Pro’s SSD (AP1024M) is. I will be asking Apple if the iMac Pro’s SSD or other system components might have been damaged or had their lifespans shorted by what happened. Period.19:27:49.564277 -0700 powerd Entering Sleep state due to 'Maintenance Sleep':TCPKeepAlive=inactiveI did not have iStat Menus installed at the time and so did not know the temperature of the other components, however, the back edge of the iMac Pro’s display felt very warm, suggesting the other components were as hot or hotter than the SSD.
