CPU Machine Check Architecture Error Dump

Received a new 16" MacBook Pro. After 2 days received the following Error Message. Any thoughts?

My machine is a few months older, a 15" 2019 retina map, and it's restarted three times in the past day with an extremely similar message. Very frustrating and as always right before a deadline. Not easily reproducible and all three times while I wasn't at the machine.

machine checks (MCA) are hardware or very low-level software or firmware— your best bet is contact Apple directly.


Call Customer Support (800) MY–APPLE (800–692–7753)

or on line https://getsupport.apple.com/


or call AppleCare Support at 1-800-APLCARE (800-275-2273)


or return it for one that works out of the box, you have a limited 14 days for exchange or a full refund.
