Most Mac applications are self-contained items that don’t mess with the rest of your system. Uninstalling an application is as simple as opening a Finder window, clicking “Applications” in the sidebar, Control-clicking or right-clicking the application’s icon, and selecting “Move to Trash.”

You can also drag-and-drop an application’s icon to the trash can icon on your dock. Or, open the Launchpad interface and drag-and-drop an application’s icon to the trash can from there.

Most applications will go straight to your trash, and you can then Control-click or right-click the trash can icon on your dock and select “Empty Trash” to get rid of that application and all the other files you’ve deleted.

However, some applications will prompt you for a password when you try to move them to the trash. These applications were installed using the Mac package installer. Uninstalling them will remove whatever system-wide changes they made.

Note that you can’t remove built-in applications by doing this. For example, try to move the Chess app to the trash and you’ll see a message saying, “Chess can’t be modified or deleted because it’s required by OS X.”
