MacBook Pro 2020 restarting/kernel panic, can anyone explain the panic log?

Hi,


My laptop has been restarting on its own recently, maybe 3-4 times over the past week. Sometimes while I'm using it, sometimes while sleeping.


My OS is fully updated (Ventura 13.5), and the kernel panics appeared both before and after the latest update. I had noticed Google Chrome added some apps on its latest update recently and got rid of those. The problems stopped for a few days, but reoccured this morning. The Chrome apps aren't back though.


I tried Apple Diagnostics but no issues were found.


I know the panic log sometimes has the misbehaving app or issue, but I have little tech nohow. Can anyone help?


My kernel panic log is attached, thank you!



MacBook Pro 13″, macOS 13.5

It appears you are using a MBPro 13" (2020) non-touchbar Intel model.


The Kernel Panic is reporting ACPI executed a fatal opcode which basically means some part of the power management executed an instruction which caused a problem. Here is another post about it:

The only thing you can really do is make sure to disconnect all external devices in case one of them is causing a problem. You can also try a clean install of macOS by using Disk Utility to erase the whole physical SSD (Intel macs only) before reinstalling macOS. An even better option would be to perform a firmware "Restore" if you have access to another Mac running macOS 12.4+ since this will reset the T2 security chip & firmware & prepare the internal SSD for an installation of macOS, although you will need to use Internet Recovery Mode (Command + Option + R) to reinstall macOS afterwards.


Then test the clean install to see if you continue to receive the Kernel Panics, again with all external devices disconnected. Do not install any third party apps and do not restore from a backup during testing just in case you bring the problem back. If a clean install of macOS under these conditions still has Kernel Panics, then it indicates a hardware issue which will need to be repaired. If the Kernel Panics no longer happen, then it may indicate an issue with some third party software or a connected device. Unfortunately the Apple Diagnostics don't detect most failures.


I think you will find it is some sort of hardware failure. Unfortunately most Apple techs don't know how to examine Kernel Panic logs so you may find it a bit difficult getting Apple to repair it unless one of their service diagnostics reports a failure, or if you can show a Kernel Panic or other issue with a clean install of macOS or firmware "Restore". It can really help if you can reproduce the issue on demand, but don't hesitate to have Apple or an Apple Authorized Service Provider examine the laptop. It really helps if they know an issue occurs with a clean install of macOS.


Good luck. Feel free to follow up when the issue is resolved.

you can contact Apple support and ask them to help determine what is going on. the first responders will follow a script very similar to what HWTech has already suggested, see if it occurs on another user, or in safe mode, or after an ERASE and clean install (no add-ons).

if they run out of ideas, ask for a specialist to contact you.


They can read the crash reports you post here if you tell them your avatar or provide a link, but they have their own ways of problem determination, so they never accept our conclusions at face value.


if they find the reason behind the crashes, they can DIRECT a service provider to change some hardware, rather than you going to service provider blind, having them tell you "passes all tests, it's fine."

Thanks for the info, I appreciate it.


That doesn't sound great, especially since I don't have any external devices being used.


I'm leaning towards keeping this Mac as my backup, and maybe switching over to a PC as my go-to. It's frustrating that an issue like this is so opaque.


I know when buying a new Mac, my Apple ID would transfer everything over, but to have this one for 3 years and all of sudden have an issue like this; man I don't know.


Thanks again for giving me the lowdown.
