Mid 2012 MacBook Pro Retina freezing and rebooting after High Sierra update
Product Name: Apple MacBook Pro Retina - Mid 2012
Processor: 2.3GHz i7
RAM: 8GB 1600 MHz DDR3
Graphics: Intel HD Graphics 4000 w/ 1536MB VRAM
Storage: 256GB SSD
OS: MacOS High Sierra 10.13.3
Since I have upgraded to High Sierra, I have had nothing but issues. My Mac, under any kind of load whatsoever, will lock up entirely, and after about 10-15 seconds, it will reboot. I can't even split screen a word document with Safari. The computer doesn't seem to be overheating.
I have tried the following:
Resetting NVRAM & SMC
First-Aiding the SSD
Creating guest account to isolate issue and removing the main account
Booting into Safe Mode
Completely wiping the laptop, removing the partitions, and rebuilding High Sierra from scratch.
I'm currently typing this off of the laptop, and since I have only this one Safari tab open, it's working fine, but if I were to do anything else, it would freeze. Are there any suggestions on how I can fix this, or any information on how I can possibly rollback to the prior OS? I was using the laptop for hours before I upgraded to High Sierra, and it was working fine. The second that I booted into High Sierra the first time has been nothing but issues.
Thanks!
MacBook Pro with Retina display, macOS High Sierra (10.13.3)
