High CPU usage while in background

I'm a long time user of Path Finder. Currently using version 10.2 (2098) on an Intel MacBook Pro 16" running macOS Big Sur.

Activity Monitor is showing 90% average CPU usage for Path Finder while the application is in the background, not being actively used for anything – i.e. no file copy/move (or any other) operations in progress. This is a constant/perpetual situation. All I have to do is start Path Finder and leave it running without interacting with it all (e.g. switch to a different space/desktop and use other applications).

The Path Finder CPU usage reported by Activity Monitor varies between 80% and 100%, occasionally dropping below 80% or exceeding 100%. The number of Threads for the Path Finder process varies between 7 and 9, and the Idle Wake Ups between 55 and 65 – again, this is while Path Finder is in the background (i.e. without interacting with it, and with no active file copy/move operations).

I use Path Finder in dual pane mode, and I generally have around 6–8 tabs in each of the two panes. There are no network or external drives (only the built-in SSD).

While not a huge concern when the MacBook Pro is plugged in (as there are plenty of cores and spare CPU capacity), it is a major issue when running off battery power.

    I just noticed the same things. Fans blasting, getting errors that I am out of application memory, something is wrong between PF 10.2 and Mac OS 11.6.1.

    Hi Radu,

    Could you send us a sample (a snapshot) of Path Finder process in a separate file? This will enable us to analyze what happens with the application.

    Here's how to get it:
    1. Open Path Finder and reproduce the problem. If the problem is dynamic (e.g. unexpected action result), please try reproducing it during the sample collection.
    2. Open Activity Monitor from the /Applications/Utilities folder.
    3. Select Path Finder in the process list. To help making a selection, type "Path Finder" in the Filter field.
    4. Click the Sample Process button in the toolbar - this will open a new window entitled "Sample of Path Finder" and a sample of the process is collected.
    5. Click Save and save the sample file.
    6. Close (Command-W) the Sample window opened in step 2.
    7. Send the sample file saved in step 5 to us.

    Looking forward to your reply!

    Best Regards,
    Path Finder Support Team
