If the app does have an “X,” then click on it to delete it.
This is either because you didn’t get the app from the App store or your Mac needs this specific app and you cannot delete it ( link). However, you might notice that not all of the apps have the “X” next to it.
Whether you want to make room for more storage on your Mac, or you just want to know how to uninstall an app, there are a few methods that you can use to delete a program off of your Mac computer.
