MacBook Air keeps restarting

Hello, guys,

For about a week now, my Macbook Air (latte 2018 model) keeps rebooting, sometimes several times.

Here is the error log:

Would a fresh installation do any good? Or is it a hardware problem?

Thanks in advance!

What are you typically doing when it panicks and restarts?

Thanks for the interest, @cornchip

Zoom calls or writing on Pages

Those two activities don’t have a lot in common. I’d suspect hardware but it’s worth trying to do a clean reinstall first if it’s happening often enough you can’t work effectively anyway. System diagnostics are most likely too sensitive to post here, but you could record them for Apple and try to trigger the crash. View > System Diagnostics… in Activity Monitor.

Thank you so much. I’ll try a clean install!

You didn’t mention an Apple Store or Apple dealer nearby, because if you had one, that would be the place to go for initial troubleshooting and eventual sending into Apple for repair. Repeated panics are often hardware-related (peripherals that you can troubleshoot by unplugging) or internal components which Apple must deal with.

When they told me my 2018 MBP needed to go back to Apple for repair, I was able to buy one of the new and very desirable M1 MacBook Air machines. Didn’t want to be without a Mac. Turns out they had the 2018 Mac repaired and back to me in a couple of days.

I’ve had this happen twice with the same 2019 MBP, once just after I got it and again a couple of months ago (AppleCare expired on Jan 06 of this year, whew!). Both times it was RAM failure that caused the random reboots.

This past week I have been experiencing several kernel panics with my mid-2019 MacBook, which began on the evening of January 15 with x86 cpu CATERR detected. I tried all the steps that were mentioned to recover a Mac from a kernel panic (including the reinstall of the OS) and they are all short-term solutions as the panics have since resumed. The Apple Store employees told me it was a software issue as I had to reinstall the OS. However they were wrong and I suspect it is now an issue with either the USB-C ports, the power supply or the motherboard. Since my Mac is 3.1 years old I am going to intend to use it as long as possible before something very bad happens.

I have renewed the AppleCare for a fourth and final year.
