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,

PERLMACOS(1) Perl Programmers Reference Guide PERLMACOS(1) NAME
README.macos - Perl under Mac OS (Classic) SYNOPSIS
This document briefly describes perl under Mac OS (Classic). If you are running perl under Mac OS X, you don't want to be here (unless you are in the Classic environment under Mac OS X). When we say "Mac OS" below, we mean Mac OS 7, 8, and 9, and not Mac OS X. DESCRIPTION
The latest perl source itself builds on Mac OS, with some additional pieces. Support for Mac OS is now in the perl core, and MacPerl is kept in close sync with regular perl releases. To build perl for Mac OS (as an MPW tool), you will need the addition of the macos subdirectory, distributed separately. It includes extra source files, config files, and make files. It also includes extra Mac-specific modules. To build the MacPerl application, you will also need the macperl directory, which includes the source files for creating the application itself. All of this is available from the development site, via HTTP (in the MacPerl Installer, which includes all the source and binaries) and anonymous CVS. http://dev.macperl.org/ The source is also in the main perl repository in the macperl branch (the 5.6 source is in the maint-5.6/macperl branch). You will also need compilers and libraries, all of them freely available. These are linked to from the SourceForge site. Go that site for all things having to do with MacPerl development. MacPerl 5.6.1 and later are supported on Mac OS 8.1 and later, for 68040 and PowerPC architectures. The MPW tool may be used on Mac OS 7.5.5 and 68030 computers. MacPerl 5.2.0r4 is also available, on the CPAN and on SourceForge. It is based on perl 5.004, and works with Mac OS 7.5.5 and 68030 com- puters. AUTHOR
perl was ported to Mac OS by Matthias Neeracher <neeracher@mac.com>. It is currently maintained by Chris Nandor <pudge@pobox.com>. DATE
