MacBook Pro 13" 2020 flashing rainbow colors when shutting down, less than 2 weeks old

I've reset PRAM, NVRAM, and SMC to no avail. Turning True Tone on and off doesn't do anything either.


The rainbow flashing returns no matter what I do.

MacBook Pro 13″, macOS 10.15

Check if you have same issue in safe mode, then you can Contact Apple Support.


Note: Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.
