Duet Display

Since at least Catalina, but persisting under Big Sur, over many versions of Path Finder up through 9.4, I find that if I plug in my iPad with Duet Display, Path Finder hangs and starts leaking memory at a few GB every few seconds until I Force Quit it (or the system hangs). The order seems to matter: if I restart Path Finder with Duet already running, it usually survives.

    Oh, and now that it occurs to me to try, I see the same issue with Sidecar and AirPlay mirroring (not sure if those are the same or different).

    Hi Mark,

    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
