BDLDaemon using >90% of CPU since last update



  • I don't have those directories. I don't use Time Machine. Still 100%. Have off for now, until a fix.

  • I'm going to wait for an application update. Until then constant scanning is off.

  • Unfortunately, the problem is old and the company doesn't want and probably can't solve it. If you search for BDLDaemon in this forum, you will see many posts from 2015 onwards. Technical support noted that they know about the problem and someday they will solve it.

    I just removed Bitdefender from different MacBooks and installed a different antivirus. Bitdefender behaves worse than any virus by killing the MacBook SSD and battery.

  • The same issue for me. I am already satisfied with Bitdefender Windows security suite for years but this issue disqualifies it on Mac. It extremely limits my musical works. Limited CPU available for Logic Pro extremely decreases number of usable plugins even the top 2018 configuration of MacBook Pro used.

    Bitdefender please solve it on your side - I am not IT guru to do magic in Terminal.

  • Recently purchased the new MacBook Air, and installed BitDefender on it. I recently renewed my subscription and wanted to maximize my use of it, but I had to uninstall it off my MBA. BitDefender was using nearly 1.5GB of memory.

  • Thank you Carolina!

    I have added /Volumes/ to the exception list (the others did not exist), and this seems to have helped immediately. Fascinating.

    Just in case it's useful to someone, instead of the "defaults write" stuff, it's possible to toggle displaying hidden files with the keyboard combination cmd-shift-period .

    I added these two directories to Exceptions, like Carolina (thnx!) suggested.


    result: no more excessive BDLDaemon activity. so there definitely seems to be a connection between TimeMachine volumes and BDLDaemon activity...

    I have a similar problem.

    How do I attach this files?


    I can not find! Where is this folder?

  • Running Big Sur on Macbook Pro but for me BDLDaemon only goes to 100% when using Safari. With Firefox all runs smooth.

  • FYI - Using the command from support:

    sudo lsof +r 1 -c BDLDaemon | grep DIR

    Helped me confirm my problem and I used Carolina's solution to resolve it!

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
