Hi

PathFinder: 9.4
macOS: 10.14.6

Recently I've noticed a regular problem of PathFinder using 90-100% CPU (ie up to one full core) when it's sitting there idle. I have multiple monitors and I often have PathFinder visible on one monitor while I'm doing other tasks. But I'm not interacting with it in any way, and it's not been left in a situation where it could be expected to use CPU (ie there's not lots of CoverFlow previews visible or anything like that).

When this starts happening it seems to continue indefinitely, until I close it and restart it. The problem then goes away for a while, and then at some point I notice it again.

It's happening right now, so I thought I would report it. I've taken two Sample dumps of it during the current high CPU usage, which I hope is sufficient for your devs to diagnose the problem.

Please let me know if additional information or diagnostic data is needed.

Many thanks

Tom

    Hi Tom, 

    Mary from Path Finder support here!

    First of all, thanks for reporting such issue!

    In this case, can you please try to follow the suggestions to reduce the CPU usage:
    1) Choose any .txt file, open Preview module preferences (gear button next to its header) and uncheck "Colorize syntax". 
    2) Restore defaults for View Settings (CMD+J). Make sure to have "Calculate all sizes" unchecked here. 

    Sorry for the inconvenience. Let me know how it goes!

    Best Regards,
    Mary

    Hi Mary

    Thanks for your response.

    I already had "Calculate all sizes" disabled, and I did not have the Preview window visible. Nonetheless I have temporarily activated Preview so I can disable Colorize Syntax, then hid Preview again as I don't use it. I hit space to preview files when I want to see them.

    Attached is a screenshot of my standard Path Finder layout.

    The problem has now occurred again, so I've also attached another sample capture. I'd had PathFinder running for 24 hours or so without issue, then over the last hour I've been using it to go through various folders to find and delete old files. Old documents, screenshots, etc. After I finished this process I noticed that it was once again stuck at 90+% CPU even though it was now idle.

    I have had this problem for years...
    The only way I found (past the standard «high CPU» response) is to close all the PF windows, and restart it.

    Would be nice to have fixed once and for all.
