Owners of the iMac Pro and the new 2018 MacBook Pro have turned to Apple forums to report several instances of kernel panics, which trace back to BridgeOS found in the Apple T2 chip. The T2 chip provides support for secure boot, encrypted storage, and the always-on 'Hey Siri' command. Apple is apparently aware but has not publicly acknowledged the issue so an estimated date for a fix is not yet known.

Yes, I am having these issues with a new 2018 MacBook Pro and have been with apple support over this issue multiple times. I've tried everything they have suggested and the computer keeps restarting.
