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 ;

I installed 10.5 (Leopard) on my G4 733 Mhz (after minor tampering with the install package, just switched a boolean FALSE to TRUE).
Everything works fine after startup, but once I sleep the computer and wake it back up, kernel_task starts using at as much CPU runtime as it can, as in past 90%.... (0 Replies)

Hi bros,
CPU speed of Sun Sparc Enterprise T5140 in data sheet is 1200 Mhz. Why it shows in "prtdiag -v" command each thread just has speed at 1165 Mhz.
Thank you,
