Uninstall Apps on macOS Using AppCleaner
Uninstalling unused applications is good practice for a number of reasons. First, it allows you to free up valuable space on your hard drive. Second, many applications run background processes that you may not even be aware of, claiming valuable CPU cycles.
Removing specific applications like TotalFinder are sometimes tedious and not straightforward. That said, there are some universal methods for software uninstallation that almost always work.
Fortunately, some applications are easy to uninstall—especially those that ship with an uninstaller. For apps that don't, you can try to safely delete the app using AppCleaner.
