I am at a loss of solutions for this problem. I keep getting these kernel panics with random reboots at the most unpleasant times.

Things tried:

  • formatted and reinstalled MacOS Catalina 15.1. thrice
  • SMC / NVRAM reset
  • file-system check on errors
  • not installing any additional software after clean re-install
  • Safe-boot

Nothing of this helped. I am still having these problems.

Any help for this? I would greatly appreciate any points for new directions.

  • @ankii No, I do not have Chrome installed. – PhilBa Nov 13 '19 at 11:00
  • apple.stackexchange.com/questions/372183/… This question had com.apple.driver.AppleSMC(3.1.9) as the problem. I see com.apple.driver.AppleEFINVRAM(2.1) in yours. Could you try what all answers and comments suggest there, but for NVRAM ? you don't seem to have tried Safe boot – anki Nov 13 '19 at 11:03
  • @ankii Thank you for the pointer. I forgot to mention that I was also going into safe boot (edited into original post). Regarding SMC & NVRAM - I was resetting this after each clean install. No luck unfortunately. – PhilBa Nov 13 '19 at 11:09
