Now....

Code:
Finishing Restore
Time remaining: 6 hours and 11 minutes

Hmmm.

MacPro has completed restored based on a Time Machine backup two days before I installed TeamViewer and the problem remains.

CPU still running at kernel_task over 1000% and very slow.

So, I need to change the title of this thread and edit it since it looks like TeamView is not the problem.

Now, I have shut down the can and have disconnected the power cable and will wait a minute and restart, to reset the SMC.

Let's see if that works!

Resetting the SMC did not work.

Activity monitor still shows CPU at 2000% for the kernel_task.

I will test to see if the problem is the SSD, next.

I tried running First Aid on the SSD but the high CPU at around 2000% makes this very slow, and the system just hangs.

The restore process did not indicate the SSD was bad, and I've tried every Apple support suggestion.

Hmmmm. This is a mystery that needs to be solved.

SSD is fine....

Hardware diagnostics show:

Code:
PMF006:  There may be an issue with the System Management Controller (SMC)

Have already tried resetting it many times, with no joy.

Hmmm.

Guess it might be time to take it to Apple?

Performance: Poor

Problem: Computer is too slow

Major Issues:
    Anything that appears on this list needs immediate attention.

    Runaway kernel_task - kernel_task is using a large percentage of your CPU.
    Poor performance - EtreCheck report shows poor performance. This is unusual.

Well, that did not tell me anything I did not already know... Smilie

  • Unloaded all third-party kernel extensions
  • Filed a bug report with Apple using my OSX beta testers account
  • Searched most every inch of the Internet.

My best guess at this point is that it is a SMC-related issue and I will have to take this round-can to Apple this week and let their techs have a go at it.

T5140 CPU Speed is 1200 Mhz or 1165 Mhz?

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, tien86... Solaris

kernel_task help

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%....... OS X (Apple)
