Mac OS X and macOS have a few restrictions about which items you can remove. The Finder and the Trash are permanent members of the Dock. There's also a separator (a vertical line or dotted line icon) that marks where apps end and documents, folders, and other items begin in the Dock. Pressing delete will permanently remove the app from your Mac. It will not put the app the in Trash. The good news is the Mac App Store will allow users to re-download purchased apps. Just make sure you have made a backup of any paid applications, (that have been purchased outside of the Mac App Store), and their registration code prior to.

Use Launchpad to delete an app

Launchpad offers a convenient way to delete apps that were downloaded from the App Store.

1. To open Launchpad, click it in the Dock or open it from your Applications folder. You can also pinch closed with your thumb and three fingers on your trackpad.
2. If you don't see the app in Launchpad, type its name in the search field at the top of the screen. Or swipe right or left with two fingers on your trackpad to show the next or previous page.
   
3. Press and hold the Option (⌥) key, or click and hold any app until the apps jiggle.
4. Click next to the app that you want to delete, then click Delete to confirm. The app is deleted immediately. Apps that don't show either didn't come from the App Store or are required by your Mac. To delete an app that didn't come from the App Store, use the Finder instead.

Learn what to do if the Dock contains an icon with a question mark.

Removing programs from a Macintosh can be very easy. In many cases, all you have to do is drag the application's icon to the Trash. Sometimes, though, applications store the files they need to run in other locations on your computer's hard drive, and finding them can take some detective work. If you are used to the uninstall option in Windows, you have a little culture shock — macOS does not have this feature built in.

Why would you want to uninstall a program? For the same reason you occasionally tidy your office or clean your garage. Clutter breeds inefficiency. Applications take up space on your hard disk and can slow your computer. Also, a new version of a program may not work correctly unless you get rid of the old one [source: Ritchie].

Most of the time, uninstalling is this simple:

1. Exit the program you want to delete.
2. Open the Applications folder, which you'll find by opening a new window in the Finder, or clicking on the hard disk icon.
3. Drag the icon of the program you want to uninstall to the Trash.
4. Empty the Trash.

When files for the application you want to delete are all stored in one location, dragging the icon to the Trash will take care of most of the work. In Mac talk, apps like this are 'bundled.' To see the files in an application's bundle, click on its icon while holding down the Control key. You should see an option that says, 'show package contents.' Uninstalling applications downloaded from the Mac App Store is even easier — just delete the application from the Applications Folder and its accompanying folder in UserLibraryContainers [source: Tanous].

For some other programs, removal is more complicated. When installed, these programs create files in several locations, often in the System Folder. The first step in removing them is to check the program's documentation to see if there is an uninstall utility. If your program has an uninstall utility associated with it, it may have been installed with the program or included on the disk that came with it. If you downloaded a disk image to install the software, sometimes you'll find an uninstaller there. Running an uninstall utility can make removing a program much easier.

You should be aware that removing an unbundled program by moving it into the Trash can leave behind orphan files on your computer. Preferencefiles are usually small and you might want to ignore them if you're just trying to free up disk space. Background files or support files can be larger, especially for multimedia programs like GarageBand [source: MacRumors]. These files are likely to reside in Library folders in your hard drive or Home folder. They will usually be labeled with the name of the program, like Office or Acrobat, or the developer, such as Microsoft or Adobe. You can search for the relevant names using Spotlight, which is included with the Mac OS. Drag the files you find to the trash to get rid of them [source: Tanous]. .

If searching through obscure corners of your computer for what could be hundreds of files sounds like something a machine could do better than you, you're right. There are plenty of software programs that do just that. They're usually your best bet for really cleaning an app off your Mac, and some of them are free. Popular examples include AppTrap, Appcleaner, and AppZapper.

Some of the files that a program might create on your hard disk are invisible. It may be tempting, especially for neat freaks, to find and delete these files. But some files are deliberately hidden because they are essential to the computer's operating system. Deleting the wrong file could land you in deep trouble [source: Landau]. The best advice is not to go where even experienced techies fear to tread. Uninstall utilities can search out and destroy these files, but doing so on your own invites trouble.

Another important thing to do is empty your Trash when you're finished uninstalling. Moving a program's icon to the Trash doesn't actually remove the files from your hard disk or clear up any space. Only when you empty the Trash is the application really gone.

Here are some other important tips:

• When you install a program, check to see how to uninstall it. Make a note if it has its own uninstall utility or instructions.
• Before you begin any uninstalling process, check to make sure your Trash is empty or contains nothing you might want to save.
• Log on as your computer's administrator whenever you uninstall. If you're uninstalling at work and don't have administrator privileges, you'll have to consult with your tech people [source: Ritchie].
• If you opt for a third-party uninstall utility, look at the features. Some developers charge for their software, but you may not need the bells and whistles. Free utilities may work fine.
• It often makes sense to leave preference files alone. If you ever reinstall the same software, you won't have to set the preferences.
• Suites of software from a developer, such as the Office suite from Microsoft, often share files. Removing the files of one component may affect the others, so it's good to be cautious with these [source: The X Lab].
• If, after you remove a program, the icon is still in your dock, you can get rid of it by simply dragging it off the dock and letting it go [source: Tech-FAQ].
