shut down multiple times

Starting today, the macbook pro keeps shutting down.

It will reboot after it rests and work fine for a few minutes, then shut down.

Some information from the error message that comes up:

debugger message panic

caterr detected

OS version 17P53000

MACOS version 19F101


Looking this up it says it could be hardware but could be software. I don't know how to start it in safe mode. Is that the next step? Or apple store?

thanks.

Mac Pro

To start up in safe Mode, hold Shift key at Startup. It does a number of interesting things.


I starts to load MacOS, then pauses and does a five minute disk repair, then proceeds. At the end of that it demands you userid and password, even if you normally auto-login.


When loading, it loads only a minimal set of Apple-Only extensions, and does not load graphics acceleration. Screen update will be wonky and slow, but ultimately correct.


It assumes defaults for as many settings as possible, including screen resolution. If you choose to make changes in safe mode, those changes WILL stick in regular mode. So this is a way to get around screen resolution set out-of-bounds, for example.


Since no third-party extensions are loaded:

"Works in safe mode, but not in regular mode" implies "It's something you added".
