Please follow the instruction and check if the issue still persists:
Open your terminal and paste the following command to check if Path Finder has been slapped with the quarantined extended attribute:
xattr /Applications/"Path Finder.app"
If you see com.apple.quarantine returned as output from that last command, then go ahead and run this next command:
xattr -d com.apple.quarantine /Applications/"Path Finder.app"
You won't get any feedback or output from that command, but that's okay because you can just run the first command again to see for yourself if the com.apple.quarantine attribute shows up again. It shouldn't. Restart your PathFinder now.
very simple: Cmd+I on a file/folder; expand "Tags and Rating"; click in "Tags"; navigate cursor to Tag to be removed; click Back keyboard button. Then for less than a second the Tag is removed and then re-appears.
Analogue to adding a Tag: Cmd+I on a file/folder; expand "Tags and Rating"; click in "Tags"; type any letter, e.g., G for the Tag Green. Then for less than a second the Tag is letter is removed.
I am forwarding this case to our developers now as a bug report.
In case you'd like to assist us, you can 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:
Open Path Finder and reproduce the problem.
Open Activity Monitor from the /Applications/Utilities folder.
Select Path Finder in the process list. To help making a selection, type "Path Finder" in the Filter field.
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.
Click Save and save the sample file.
Close (Command-W) the Sample window opened in step 2.
Send the sample file saved in step 5 to us.
Don't hesitate to contact us should any additional questions arise.
