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.

The "bsdtar" process was hard on my MacBook Pro and created over 300% CPU load.

Update 03.02.2020/XNUMX/XNUMX: The best solution is through the settings

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!

1. Problem-solving option: restart did not help

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.

2nd option: Googling - the cause is the parallel toolbox

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.

Remove Parallels Toolbox with CleanMyMac

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.

The Parallels Toolbox can be conveniently deactivated using the CleanMyMac optimization tool.

Removal of the bsdtar trigger with on-board resources

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:

  • LaunchAgents
  • LaunchDaemons
  • StartupItems

I have two screenshots here that show you which folder you should look in:

The LaunchAgents and LaunchDaemons folders are the first choice when looking for persistent programs that keep booting up.

The StartupItems are probably not the place where the Parallels Toolbox is, as only the programs are here that are started once when you restart. These can be ended very easily while the bsdtar process was started again and again.

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.

Small request to you

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.

Do you like my blog? Then I would be happy to receive a short review on Google. Easy leave something here for a moment - that would be great, thank you!

    Strange, I've never had problems with the Parallels Toolbox (version 16) on my Macbook Pro 15. I think there is an error in the configuration.

    • Sir Apfelot says:

      I do not think so. Rather, I guess it was a Parallels update that was done automatically. Or it was the 10.15.13 Catalina update. But I haven't reconfigured anything ... but who knows. Maybe I had set something wrong earlier. However, I had never booked the paid version of Parallels Toolbox. So it is a mystery to me why it suddenly twitches.

    I had the problem myself.
    However, I was able to fix it by deactivating "Start at computer startup" in the settings of the toolbox.

    • Sir Apfelot says:

      Hello Georg! Thanks for the hint. This is definitely the more elegant solution. Mine is more like the mallet. : D

    • Robert says:

      I've had the problem for a long time.
      Only yesterday I came up with Georg's solution to the problem. I have deactivated "(Windows) Start at computer startup" in the Parallels settings.
      Let's see if it's gone now.

  3. Robert says:

    I had that problem too.
    Deactivating the "Start at computer startup" option in Parallels' settings instead of in the Toolbox has the same positive effect.

  4. Simon says:

    I only used the countdown timer briefly from the II toolbox. However, when closing several "bsdtar" processes crept in.

    The manual stop of the bsdtar processes in the activity display ("cross" top left) was enough for me.

    Since then, the II toolbox has been deactivated in my restart.

    Thank you, this post really helped me! My iMac 27 ″ was as lame as a 386 ... The Parallels Toolbox "Start when the computer starts" and restarting it helped - the fan is now off!
