I had some trouble finding details of how to remove VyprVPN from my Mac with OSX Mavericks 10.9.3 installed
After contacting GoldenFrog Support this is the information that they gave me:
In order to completely uninstall VyprVPN from your Mac.
Please log out of VyprVPN and drag the application to the trash.
Then, quit the vyprvpnservice listed in Activity Monitor.
If you have trouble quitting the process, open Terminal on your Mac, and type the following:
sudo launchctl unload /Library/PrivilegedHelperTools/vyprvpnservice
Press return, and you’ll be prompted for your password, which should be your login password (you won’t see characters while typing the password).
After running the command and entering your password, the list of files that are displayed can be removed:
If you have difficulties locating the files listed, you can go directly to the path by pressing command+Shift+G and pasting the file paths.
