Chapter in this post:
Yesterday morning I came to my MacBook Pro and was amazed that it was busy ventilating the air, even though it only ran in standby all night. A look at the "Activity Monitor" utility immediately showed the cause: a process called "bsdtar" started several times and ran a bit amok. Overall, the process easily occupied over 300% of the CPU - the finder was correspondingly slow to operate. In any case, using the Mac to work like this wasn't an option, so a solution was needed quickly.
A reader has just informed me that he has solved the problem by deactivating "Start on computer startup" in the Parallels Toolbox settings and then restarting the Mac. This solves the problem quickly and you don't have to work in the library folder, as I have described below. @Georg: Thanks for the hint!
Whenever I have a Mac problem, I always give the Recommendation from the specialists at IT Crowd a chance: switch it off and on. It feels like it can fix over 90% of computer problems, but unfortunately in this case it had no effect. Immediately after the start, six bsdtar processes started up again, which occupied the MacBook Pro.
Since I got stuck with the restart, I asked Google for help and returned with the search query "mac process bsdtar high cpu usage"directly at the Parallels Desktop forum landed. The recommendation of the users there: uninstall the Parallels Toolbox.
Since you have to remove the LaunchDaemon or the LaunchAgent from Parallels Toolbox in particular, you cannot avoid going to the system's library folder. Important: for me, this file was in the library folder directly in the top directory of the system hard drive and not in the library folder that you can find under your own user folder.
I made it easy for myself and over CleanMyMac X (a highly recommended tool that is also available in Setapp subscription Parallels Toolbox is deactivated via the option "Optimization> Startup Agents" and "Optimization> Login Items". Unfortunately, I didn't take a screenshot before removing it, so I no longer know exactly which folder this program is in.
If you want to work without such little helpers, go to the top level of the hard drive as an admin user (for me it is classically called "Macintosh HD"). There you will find the folder "Library" and it is best to look in these three folders to see if you can find something called "Parallels Toolbox" or something similar:
I have two screenshots here that show you which folder you should look in:
You then drag the corresponding file onto the desktop, for example, so that the Mac no longer "finds" it in the corresponding folder and then restarts the Mac.
For me, the CPU and the process calmed down after this action bsdtar has no longer drawn negative attention to itself.
I hope the short - unfortunately somewhat incomplete - guide will help you find the CPU rascal when bsdtar goes crazy. If you can find out the exact name of the file, please leave me a short comment here. I would like to add it above for the sake of completeness.
