Had a 5 min power outage and have a UPS. Was able to shut system down before battery drained. Now system goes to sleep and upon wakening I get message "Your computer was restarted because of a problem." The report indicates a "Panic Report" (see attached).
I've updated my OS to macOS Mojave v 10.14.6 and the problem persists. My machine is a 2017 iMac 27", with 3.8 GHz Intel Core i5, 32 GB 2400 MHz DDR4.
IF it's a 27" with upgraded RAM then my bet is:
Failed RAM
Unseated RAM
Incorrect RAM
You will need to troubleshoot by elimination which one it could be. If you prove beyond a shadow of a doubt it is not RAM, then it's probably some other hardware like a failing HD.
Your computer is experiencing Kernel Panics, please post the last entire KP report you find in the Console logs.
UPDATE: Problem resolved. Quite possibly a lose RAM module. I checked the modules and then ran Apple's <Option>-<D> when booting. Machine operating normally without error message. There is one other possibility - Recently installed AnyDesk about two days before the power failure and during each reboot AnyDesk initiated. I deleted the program prior to the test and did not check if that was the problem. Thanks again for the help. JR
Thank you. It is a 27” with Apple factory installed RAM (4 x 8 GB 2400 MHz DDR4). We live near a stone quarry that uses explosives once a day M-F. So after 2 years I guess it’s possible the ram modules could come lose or maybe went bad. I’ll check that out. I hope it’s not my HD, however my old machine went through 2 HDs. I’ll provide an update on the findings. Thanks again. JR
Thank you. Here's the log I think you are asking for:
iMac continues to restart after waking from sleep.
