Uninstalling an app isn’t as straightforward as you would think. When you drag and drop an app into the Trash, then empty it, the main app itself may be gone, but many associated files and folders are left behind. There are 2 ways to get rid of them.
Noob - Install an uninstaller to uninstall an installed application
Pro - Open Terminal and run few commands to get rid of junk files
Even for a Pro, finding all files and remembering those commands may not be easy. That’s why I curated a list of commands which can be used to completely uninstall an application.
