Yes, I was referring to the Finder icon in the toolbar. In addition (and I hadn't tested this until today), the right click contextual menu item doesn't work and the key shortcut option-command-F similarly doesn’t work.
I use this function a lot as I there are certain files I like to view in Finder. Any other ideas?
Please also follow the instructions below and check if this issue still persists:
Make sure that Path Finder is located in the Applications folder
(in case you are using macOS Mojave) Use System Preferences > Security & Privacy > grant Full Disk Access to Path Finder
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, and now Path Finder is freed from Apple quarantine jail. Restart your PathFinder now.
Don't hesitate to contact us should any questions arise.
