Brand New Macbook Pro Keeps Restarting

Hi everyone,


Today I received my brand-new Macbook Pro 16" - it's the 2.6 GHz 6-Core Intel Core i7 edition with 16GB RAM.


While installing a few programs earlier the Mac just randomly shut down and restarted - before it happened, the fans sounded as though they were roaring up to "full throttle" before it went dead completely and restarted. I've just upgraded from a 2015 13" Retina Macbook Pro and have only installed apps which worked fine on my old laptop. I find it hard to believe a brand new Macbook Pro would be running into these issues - does anyone have any suggestions? I've pasted the last error message below:


I'm at a bit of a loss of what to do, as I'm not running overly intensive tasks ( I didn't think - Google Backup & Sync is all I can really think it may be, but that ran fine on my old Mac with much worse specs!


Oh, I should also point out the Mac is updated and running Catalina 10.15.5


Thanks in advance

Please read If your Mac restarted because of a problem - Apple Support.


- does anyone have any suggestions?


Contact Support. A Kernel Panic is not normal and should not be tolerated.
