Operating Systems OS X (Apple) 12-Core MacPro (2013) kernel_task over 1200% Post 303033908 by Neo on Sunday 14th of April 2019 02:15:37 AM

12-Core MacPro (2013) kernel_task over 1200%

Yesterday someone asked me to install TeamViewer and share my Mac screen with them while on a conference call.

I shut down my Mac before sleeping and woke up to some major problem with my 12-core CPU in hyperdrive, and the system activity monitor showed my Mac kernel_task was at 1,200% and the fan spinning so fast it sounds like a 737 Max 8 fighting its on AI.

Seems all that great "screen sharing" of TeamViewer added some kernel extension (kext) to my Mac and just destroyed it. I have never seen a problem like this since I owned this 12-core MacPro.

Update: The same problem persists after doing a full restore from a backup before I installed TeamViewer, so my apologizes to TeamViewer.

So, I'm lucky I had a backup from two days ago and am now completely erasing my disk to restore from backup:

It started out with a system message that the recovery would take 88 hours, but now it down to 34 hours, LOL.

I guess TeamView is not designed for high end Macs with 12 cores ;
