    Could you send us a sample (a snapshot) of PathFinder 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.
    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,

    I also see this issue frequently.

    • As soon as I start PF8, the combination of PF8 + coreservicesd will take 60-100% CPU, and the fan kicks in shortly thereafter.

      • Stopping PF8 and restarting will sometimes - not often - circumvent the problem.

    What exactly might it be doing, or trying to do?

    Hi Hank,

    We are looking into this issue but it would really help if we could have your details.

    May I ask you to share more details on your current version of OS and Path Finder? When does the issue show up? Are you able to reproduce it reliably or it happens by itself? 

    Please feel free to write us back and we will be happy to assist you.

    Best Regards,
    Path Finder Support Team
