My #Apple 16" M1 #MacBookPro has just rebooted itself... again. It was fully charged; I closed the lid and left it for a few minutes to get a cup of tea. When I came back it re-booted. It's happened a few times recently. Running Sonoma 14.8.5. Anyone have any ideas what could be happening? Running #BitDefender which seems happy...

@carusb It should keep logs somewhere of why it's doing it.

Are auto updates on? I'd turn those off to see if that changes how it behaves.

If there hardware tests to run I'd try those. Could have a faulty memory chip. That can cause havoc.

@serichards Auto updates off, which is how I've managed to stay on Sonoma... No idea where any logs might be, or how to run hardware tests. (Under System Information, Diagnostics says No information Found). Full BitDefender scan, nothing found.

@carusb Think I used the D option on start up to run diagnostics before.

Also worth ruling out dust and over heating. Have you got a blower thing you could blow through the vents with while it is turned off?
