Kernel Panic

My computer restarted unexpectedly and this was the reason that was given

CATERR is a catastrophic Hardware error.

20P411 is likely some version of Big Sur.

what MacBook Pro is this by model-year? Intel or Apple-silicon?

the rest of the panic report may have more information.

Kernel Panic Reports are stored at:

/Library/Logs/DiagnosticReports

If you copy and paste that string into:

Finder > Go menu > Go to Folder

it will take you to where those reports are stored.

They are named with Date&Time and start or end in ‘panic’

If you find one, please post the entire report here, by using the “additional text” Icon in the reply footer (looks like a paper with writing).

Please don’t post more about 20 lines of any other types of reports — they are interminable, and any information useful for this purpose is on the first screenful.

There are three quick take-aways from any panic report.

1) The panic-reason,

2) the extensions present at the "scene of the crime", and

3) the BSD process in which the problem occurred.

One more item that is important is the names of any third-party Extensions you have added. They are shown FIRST in the extensions loaded section

That is a lot of mostly gibberish, but the words "BAD MAGIC" appear fairly early in the gibberish. The tends to implicate the T2 chip and communicating with the T2 chip as the culprit.

If this recurs, you likely will need service.

¿what is the date of your most recent backup, and by what method?

Consider using Built-in Time Machine. Take steps to acquire an external drive as soon as possible. If you buy one, a drive 2 to 3 times or larger than your boot drive is preferable for long term trouble-free operation. Do not pay extra for a drive that is fast. (You can get by for a while with a "found" smaller drive if necessary, but it will eventually become annoying).

Attach your external drive and use

System preferences > Time machine ...

... to turn on Time Machine and specify what drive to store your Backups on. It may ask to initialize the new drive, and that is as expected.
