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 ;

NAME
lib::core::only - Remove all non-core paths from @INC to avoid site/vendor dirs SYNOPSIS
use lib::core::only; # now @INC contains only the two core directories To get only the core directories plus the ones for the local::lib in scope: $ perl -Mlib::core::only -Mlocal::lib=~/perl5 myscript.pl To attempt to do a self-contained build (but note this will not reliably propagate into subprocesses, see the CAVEATS below): $ PERL5OPT='-Mlib::core::only -Mlocal::lib=~/perl5' cpan DESCRIPTION
lib::core::only is simply a shortcut to say "please reduce my @INC to only the core lib and archlib (architecture-specific lib) directories of this perl". You might want to do this to ensure a local::lib contains only the code you need, or to test an App::FatPacker tree, or to avoid known bad vendor packages. You might want to use this to try and install a self-contained tree of perl modules. Be warned that that probably won't work (see "CAVEATS"). This module was extracted from local::lib's --self-contained feature, and contains the only part that ever worked. I apologise to anybody who thought anything else did. CAVEATS
This does not propagate properly across perl invocations like local::lib's stuff does. It can't. It's only a module import, so it only affects the specific perl VM instance in which you load and import() it. If you want to cascade it across invocations, you can set the PERL5OPT environment variable to '-Mlib::core::only' and it'll sort of work. But be aware that taint mode ignores this, so some modules' build and test code probably will as well. You also need to be aware that perl's command line options are not processed in order - -I options take effect before -M options, so perl -Mlib::core::only -Ilib is unlike to do what you want - it's exactly equivalent to: perl -Mlib::core::only If you want to combine a core-only @INC with additional paths, you need to add the additional paths using -M options and the lib module: perl -Mlib::core::only -Mlib=lib # or if you're trying to test compiled code: perl -Mlib::core::only -Mblib For more information on the impossibility of sanely propagating this across module builds without help from the build program, see <http://www.shadowcat.co.uk/blog/matt-s-trout/tainted-love> - and for ways to achieve the old --self-contained feature's results, look at App::FatPacker's tree function, and at App::cpanminus's --local-lib-contained feature.
