Comp just shut down. Checked the logs and it says:

Previous shutdown cause: -20

A shutdown causes page says:

-20 BridgeOS T2-initiated shutdown. The T2 chip in your 2018+ MacBook Pro or other Mac (list in link) initiated a shutdown.

This is a fairly new computer, I'm not sure what's going on. I've experienced a bunch of x86 CPU CATERR detected and AppleEmbeddedPCIeUpLinkMgmt kernel panics.

Should I just go and get it checked out?

    Most definitely! The fact you’re seeing hardware related kernel panics is concerning. Get it checked out especially if it’s still under warranty

Just as an update because this question keeps getting upvoted:

it was a logic board issue - apple replaced the logic board under warranty definitely don't sleep on this issue


Fairly new computer I would 100% talk with Apple support online to see what they recommend. Might be fine, but why not take advantage of the paid support for new hardware.
