Hello dears. I bought a MacBook Pro 2021 and started rebooting on its own after a year of normal use. Typically, spontaneous reboots occur after exiting sleep mode, after 7-10 seconds. Also, sometimes reboots occur due to inserted SSD media or a USB mouse into the USB-C. I decided to update the system to the latest. I went through all the updates and installed Sonoma 14.5. There seem to be fewer reboots, but unfortunately this has already happened several times again. Help please, what could be the problem? Thank you

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

all known to cause issues on the macOS

unplug all non-essential peripherals when testing

To trouble shoot further you can:

—A SafeBoot Use safe mode on your Mac - Apple Support will sort many anomalies

Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled temporarily.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

This test will tell you if third party interference; most extensions etc are not loaded in safe boot mode.

—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support

This will tell you if it a universal issue or isolated to your user/admin account. 

Thank you very much for your help.

In general, I deleted ALL the applications one by one, nothing helped. Spontaneous reboots remained the same as they were - after the only first update from Monterey to Sonoma, reboots became less frequent, including after turning on the USB devices, there were fewer reboots, but they did not go away completely. Everything is the same, after sleep mode, sometimes - spontaneous reboots occur. And very rarely spontaneous TURNING ON OF THE MAC!

I remembered that this began after installing some programs, perhaps Adobe and changing the sleep function. It seems I turned it off through the terminal, and then turned it on again.

But now, a NEW PROBLEM has appeared)))

After installing this ****** update, the Mac began to work even more glitchy and slower and this is not self-hypnosis. I think I am far from the only one who thinks that MAC updates, both on the iPhone and on the Mac, only make things worse. Actually, this is the same in this case. Please advise - what is the best way to reinstall the system and roll back to Monterey? I'll also do a full format, maybe it will help... I've never done this before...

I'm currently testing the Mac in safe mode. If there are no reboots in this mode, what does this mean?

Thank you very much in advance!

hello

yes, the problem is not solved.. but it has also gone away completely.. now I have decided to roll back the system to Monterey and completely format the hard drive.. What other advice could you give? Because it is a very strange thing... it even turns on itself sometimes.. as if there is some malicious virus inside.. the hacker gives the command to turn on the computer..)) and this mainly happens when the laptop is in the Wi-Fi Internet access zone.. but it also happened when there is no Internet... Thank you!
