apple mac keeps rebooting

Mac (Retina 5K, 27-inch, Late 2015) OS Mojave 10.14.6 3.2 GHz Intel Core i5 24 GB 1867 MHz DDR3

Hi everybody.

I tend to leave my machine on and asleep overnight and wake up on a mouse click the next day.

During the past few weeks I open with a mouse click to find it has rebooted sometime since the previous night. The first and second time it did so, it generated a report which I both saved and sent to Apple.

Not that I could understand the report, but I kept saved it in case some of you guys might want some info from it. However, no matter where I look I can no longer find the report.

I tried going into Console, but I don't know what I'm doing, it's like staring into the abyss!

The event doesn't happen everyday, just randomly, and it no longer generates the report.

Can anyone offer any advice or is my computer dying? I'm grateful for any advice!

Many thanks

Jim

Hi Bob, I followed the guidance you gave, but I'm not getting any .panic or .contents.panic files showing even when I toggle hidden files. I've attached a screenshot of what I'm seeing. I also attached the text of a file called com.apple.WebKit.WebContent_2021-05-01-185957_Jims-iMac.wakeups_resource.diag

which looks very like a file which showed up when this problem first occurred.

I'm sorry if this is all rubbish, I can just hope it has some meaning! Kind wishes, and thanks again! Jim

Etrecheck can tell us if you are running something in the background that could be causing problems.

Please post one or more panic reports

Finder -> Go (menu) -> Go to folder -> /Library/Logs/DiagnosticReports

Command-Shift-Period will show invisible files. Look for files that end in the word .panic or .contents.panic and post them in an Additional Text box

Press Command-Shift-Period to hid the Finder invisible files again.

Then the Mac is not generating kernel panics.

The only time I saw this behavior, was when I had a memory hog app, consumed over 100GB of swapfile space, and die without a panic report. It took me a while to figure this out. You could use

Applications -> Utilities -> Activity Monitor -> View (menu) -> All Proceesses -> Memory (tab)

to monitor your apps for memory usage, and see if over time there is an app that creating up and up in memory usage, especially when you think it is getting close to when you would normally reboot.

Hi Bob,

Many thanks for your help.

I'll do as you suggest, and monitor over a period of time.

My usage pattern in terms of both time and programmes is pretty consistent, so

the problem should expose itself fairly quickly.

Many many thanks again for giving your time to this.

Very kind wishes,

Jim
