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 ;

Over six hours into this MacOS Time Machine external USB restore process, and the progress is very slow:
Looks I will not be coding for the forums for a few days because it is really a pain to develop software on a 13" MacBook Air.
I'm starting to wonder if my 250GB SSD is going bad. Seemed fine before, no errors at all. I'll have to test it when (if) this very slow recovery process finishes.
Seems to be restoring from my USB external drive at between 4 and 5 GB per hour. That means there is at least nearly two days left to go.
All was fine until I installed TeamViewer yesterday; but I'm not convinced this problem is caused by an TeamView kernel extension.
OS: Latest Version of MacOS Mojave
Box: 12-core MacPro (Late 2013) with 64 GB RAM and a 250GB SSD.

Nineteen hours into this caper, restoring an average of 3.5GB per hours over an external USB drive:
But the most important event of that time period was that Tiger Woods won his 15th major championship and his 5th Masters, shaping and creating the best sports comeback story of our time.
WARNING!
Just upgraded my MacPro (2013) from Catalina 10.15.2 to 10.15.3.
After the routine download and restart for upgrade installation, the Mac would not boot. Totally crashed.
Now, I'm in the process of a 15 hour restore from my last time machine backup.
I'm not very happy with... (3 Replies)

Hey MacPro users.
I just bought a refurbished 13-Core MacPro with 64GB of RAM for a cybersecurity gaming project I'm working on. Could not wait for the new MacPro in 2019, so this will have to do:
2013 Apple Mac Pro 2.7GHz 12 Core/64GB/256GB Flash/Dual AMD FirePro D700 6GB 6,1
Now, I'm... (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,

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)
