Anyone know how to read kernel panic reports? Here's mine

[tuqqer]

Been trying to troubleshoot my wife's MBA (MacBookAir9,1) 13" Intel for the last couple weeks. She's getting kernel panic complete shutdowns multiple times a day.

If anyone knows how to translate these crash reports, I'd love any insights you may have.

Some details:

- 256HD, 8G RAM
- Purchased new from Apple 18 months ago
- No odd 3rd party software installed (just a few standards, like Dropbox, Office 2019, 1Password)
- I've run Disk Utility from startup Recovery (Command-R at startup)
- I've reset both NVRAM and SMC
- 40G free storage (filled up 210, including the "purgeable" amt of 100GB)
- have run Malwarebytes and Onyx, just for kicks. Nothing weird.
- normally has external monitor and USB hub attached, which I thought might be the issue, but I ran the MBA this morning for a few hours without any plugins, and it did 2 kernel panics while attached to nothing except the original Apple charger.

I'm now in the process of reinstalling Big Sur from the Recovery method. Another hour to go on that.

Looks like Mail crashed but there's really no actionable info here.

Right in the middle there is a line that says:

"I wish I was an M1 MBA" :emoticon-animal-004:

I agree with mail. Can she rebuild her inbox?

That's the only line of code I was able to comprehend, too. Especially working on it over the last week, I kept thinking, did all my former Intel machines really run THIS SLOW ????

Very cool info on Mail. She's not one to clean Mail things up much (I've tried teaching her), so this could be the lesson that gets her to start keeping a lighter bunch of mail.

thanks all.

FWIW, my mail takes up about 175 GB, and runs smooth as a top, without any maintenance.

I never toss client emails out. I have 50 GB of sent emails, and the other 125 is split between another dozen or so mboxes. my client ones range from 10-25 GB. Some send me attachments galore.

[Grateful11]

I'm still running Sierra on a 2010 iMac and Mail runs stable. Three email accounts with about 300,000-400,000 emails in it that needs to be gone through.

[tuqqer]

Could just be a software glitch then, that the reinstall may fix. I'll post back the results.
