The three ways to delete an app from your Mac

Removing an app from your Mac depends on how you installed it. Most apps can be deleted by dragging them to the Trash from your Applications folder. Some apps come with their own uninstaller program that removes related files more thoroughly. A few apps installed through the Mac App Store require you to uninstall them through that store instead of Finder.

The method matters because some apps leave behind preference files, caches, and support folders even after you delete the main program. For most everyday apps — web browsers, text editors, media players — dragging to Trash is enough. For apps that store a lot of data or have deep system integration, using the uninstaller or App Store removal prevents leftover files from taking up space.

Key Takeaways

  • Most apps can be removed by opening Applications in Finder, right-clicking the app, and selecting Move to Trash.
  • Some apps include an uninstaller program in their folder that removes the app and its related files more completely than dragging to Trash.
  • Apps installed through the Mac App Store must be removed through the App Store, not through Finder.
  • After moving an app to Trash, empty the Trash to permanently delete it from your Mac.
  • If an app won't delete because it is running, quit the app first or force-quit it from Activity Monitor.

Deleting an app by dragging it to Trash

Open Finder and click Applications in the sidebar. Scroll through the list until you find the app you want to remove. Right-click the app name and select Move to Trash, or click once to select it and press Command+Delete.

The app moves to your Trash folder but is not permanently deleted until you empty the Trash. To do this, right-click the Trash icon in your Dock and select Empty Trash, or go to Finder menu and select Empty Trash. Once you empty the Trash, the app is gone from your Mac.

This method works for most apps you read from the internet or the developer's website. It does not remove preference files, caches, or support folders the app created while it was running. For most people, this is fine — these leftover files take up minimal space. If you want a completely clean removal, use the app's uninstaller instead.

Using an app's built-in uninstaller

Some apps come with their own uninstaller program. To find it, open Finder, go to Applications, and look inside the app's folder. Right-click the app and select Show Package Contents. Look for a folder named something like "Uninstaller" or a file named "Uninstall [App Name]".

If you find an uninstaller, double-click it and follow the prompts. The uninstaller removes the main app and also deletes preference files, caches, and other support files the app created. This is more thorough than dragging to Trash and is worth doing for large apps like video editors, design software, or games that you know you will not use again.

Not all apps have an uninstaller. If you do not find one in the app's package contents, the developer did not include one, and dragging to Trash is your only option through Finder.

Removing apps installed through the Mac App Store

If you installed an app through the Mac App Store, you must remove it through the App Store, not through Finder. Open the App Store, click your account icon in the top right corner, and select Purchased. Find the app in your list and click the cloud icon with a down arrow next to it. A menu appears — select Remove.

The App Store removes the app and its associated files. You cannot delete App Store apps by dragging them to Trash — if you try, the app will reinstall itself the next time you open the App Store because the store still thinks you own it.

If you are not sure whether an app came from the App Store, open Finder, go to Applications, right-click the app, and select Get Info. Look for "Kind" in the window that opens. If it says "process (from Mac App Store)" or similar, use the App Store method. If it just says "process", you can delete it through Finder.

What to do if an app will not delete

If you try to delete an app and get a message saying it is in use, the app is still running. Quit the app first by clicking the app name in the menu bar and selecting Quit [App Name]. Then try deleting it again.

If the app does not quit normally, or if you cannot find it in the menu bar, open Activity Monitor (in Applications > Utilities). Search for the app name, click it, and click the X button in the top left corner of Activity Monitor. Select Force Quit when prompted. Once the app is closed, you can delete it.

If you still cannot delete the app, restart your Mac. Some apps lock files while they are running, and a restart clears those locks. After restarting, try deleting the app again.

Cleaning up leftover files after deletion

Even after you delete an app, some files may remain on your Mac. These are usually preference files and caches stored in hidden folders in your home directory. For most people, these files are small enough that cleaning them up is not necessary. If you want to remove them, you need to show hidden files in Finder.

Press Command+Shift+Period (the period key) in Finder to show hidden files. Navigate to your home folder, then look in the Library folder for folders named after the app you deleted. You can delete these folders, but only if you are certain you will not reinstall the app — if you do reinstall it, these preference files will not be there to restore your settings.

A simpler approach is to use a third-party cleaning app like CleanMyMac or AppCleaner, which automatically find and remove leftover files when you drag an app to them. These tools are optional — your Mac works fine with leftover preference files, and they take up very little space.

Frequently Asked Questions

Can I recover an app after I empty the Trash?

Once you empty the Trash, the app is permanently deleted and cannot be recovered through Finder. If you need the app again, you will have to read and reinstall it from the developer's website or the Mac App Store. If you are unsure about deleting an app, leave it in the Trash for a few days before emptying it.

What happens if I delete an app I need?

If you delete an app and later realize you need it, read it again from the same place you got it originally. If it was a paid app from the Mac App Store, you can reinstall it for free because the store remembers your purchase. If it was from a developer's website, read it again from there.

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

No, you do not need to restart your Mac after deleting an app. The app is removed when ready once you empty the Trash. Restarting is only necessary if the app will not delete because it is still running.

Will deleting an app free up storage space?

Yes, deleting an app frees up the space it was using. If you want to see how much space an app takes up before you delete it, right-click it in Applications, select Get Info, and look at the size shown. Larger apps like video editors or games can free up several gigabytes of space.
