The fastest way to remove an app from your Mac

The simplest method is to open Finder, click Applications in the sidebar, find the app you want to remove, and drag it to the Trash. That's it — most apps will disappear completely. Drag the app icon to the Trash bin in your dock, or right-click the app and select Move to Trash. Empty your Trash afterward to free up the space the app was using.

This method works for roughly 80 percent of Mac applications because they're self-contained — all their files live in one folder. When you move that folder to Trash, the app is gone. However, some apps scatter files across your Mac in hidden locations, and dragging to Trash won't remove those leftover pieces.

If you're not sure whether an app left behind files, or if you want to be thorough, the next sections cover how to check and how to remove those hidden pieces.

Key Takeaways

  • Most apps can be removed by dragging them from the Applications folder to Trash, then emptying the Trash.
  • Some apps leave behind preference files and support folders in hidden Library directories even after you delete the main app.
  • You can view hidden files in Finder by pressing Command+Shift+Period, then look in ~/Library/Application Support and ~/Library/Preferences for leftover app files.
  • Uninstaller programs like AppCleaner can find and remove these hidden files automatically, but manual deletion works just as well if you know what to look for.
  • Restarting your Mac after deletion ensures any running processes from the app are fully closed.

Finding and removing hidden app files manually

When you delete an app by dragging it to Trash, macOS leaves behind preference files and support folders. These don't take up much space, but if you want a completely clean removal, you need to find them. The files are hidden by default because they're not meant to be touched during normal use.

Open Finder and press Command+Shift+Period (the period key). This toggles hidden files on and off. You'll see folder names appear that start with a dot, like .DS_Store. Now navigate to your home folder — click your username in the Finder sidebar under Favorites. Look for a folder called Library. Open it.

Inside Library, open the Application Support folder. Search for the app's name or the company that made it. You'll find a folder with settings and data the app created. Delete this folder. Then go back to Library and open Preferences. Look for files that start with the app's name or company name — they usually end in .plist. Delete those files too. When you're done, press Command+Shift+Period again to hide the hidden files.

This approach takes a few minutes but guarantees nothing is left behind. If you're not comfortable navigating hidden folders, the next section covers tools that do this work for you.

Using an uninstaller tool to remove everything at once

Apps like AppCleaner, CleanMyMac, and Uninstaller scan your Mac for all the files an app created, then remove them together. You drag the app onto the tool's window, it shows you everything it found, and you click Remove. This is faster than hunting through hidden folders yourself.

AppCleaner is free and does one job well — it finds and removes app files without trying to sell you other features. Download it from the Mac App Store or from AppCleaner's website, open it, drag the app you want to remove into its window, and click Remove. It will show you a list of everything it's about to delete so you can review it first.

The trade-off is that you're installing another app to remove apps. If you only delete a few apps per year, manual removal through hidden folders is probably faster overall. If you regularly install and remove apps, an uninstaller tool saves time.

What to do if an app won't delete

Sometimes an app is running in the background and won't let you delete it. You'll see an error message saying the file is in use. The fix is to force-quit the app first. Press Command+Option+Escape to open the Force Quit window, click the app's name, and click Force Quit. Then try deleting it again.

If the app still won't delete, restart your Mac. When your Mac restarts, the app won't be running anymore, and you'll be able to move it to Trash. This solves the problem in nearly all cases.

Occasionally an app is protected by your Mac's security settings. If you see a message saying you don't have permission to delete it, right-click the app, select Get Info, and look for a Locked checkbox at the bottom. If it's checked, click the checkbox to unlock it, then try deleting the app again.

Removing apps from the Mac App Store

Apps you downloaded from the Mac App Store can be removed the same way as any other app — drag them to Trash. However, you can also remove them directly from the App Store app itself. Open the App Store, click your profile picture in the top right corner, go to Purchased, find the app, and click the cloud icon with a down arrow next to it. This removes the app from your Mac but keeps a record that you owned it, so you can reinstall it later without paying again.

This method doesn't remove hidden preference files the way dragging to Trash does, so if you want a complete removal, use the Trash method instead. The App Store method is useful if you think you might want to reinstall the app someday.

Freeing up space after deletion

After you move an app to Trash, it still takes up space on your Mac until you empty the Trash. Click the Trash icon in your dock, then click Empty in the top right corner of the window. The space is now freed up and available for other files.

If you deleted a large app and want to see how much space you recovered, open Apple menu, click About This Mac, then click Storage. You'll see a breakdown of what's using space on your Mac. The storage number updates after you empty the Trash, so check back in a few seconds if it doesn't change immediately.

Frequently Asked Questions

Will deleting an app remove it from all my devices?

No. Deleting an app from your Mac only removes it from that Mac. If you have the same app on an iPhone, iPad, or another Mac, it stays there. You have to delete it separately on each device. If you want to prevent it from reinstalling automatically, turn off iCloud sync in System Settings.

Can I recover an app after I empty the Trash?

Once you empty the Trash, the app is gone and cannot be recovered. If you downloaded it from the Mac App Store, you can reinstall it for free from your Purchased list. If you downloaded it from elsewhere, you'll need to download it again from the original source.

What if I only want to hide an app instead of deleting it?

You can hide apps from Launchpad or Spotlight without deleting them. In System Settings, go to General, then Siri & Spotlight, and uncheck the app's name. It won't show up in searches or Launchpad, but the app files remain on your Mac and you can unhide it anytime.

Do I need to restart my Mac after deleting an app?

You don't have to, but restarting ensures any background processes from the app are fully closed. If an app was running when you deleted it, a restart guarantees it won't try to run again. It's a good habit after removing apps you used frequently.

Is it safe to delete files from the Library folder?

It's safe to delete preference files and support folders for apps you've already removed. Never delete files from Library that belong to apps you still use, and never delete system folders like Caches or Logs unless you're sure what you're doing. When in doubt, use an uninstaller tool instead of deleting manually.
