The fastest way to remove an app from your Mac
The simplest method is to drag the app to the Trash. Open Finder, click Applications in the sidebar, find the app you want to remove, click and hold it, then drag it to the Trash icon in your dock. Release the mouse. The app is now deleted. Empty the Trash afterward by right-clicking the Trash icon and selecting Empty Trash — this frees up the space the app was using.
Some apps leave behind small files even after you move them to Trash. These leftover files (called support files) usually take up minimal space and won't affect your Mac's performance. If you want to remove these as well, you'll need a different approach, which we cover below.
The drag-to-Trash method works for nearly every app on your Mac. It's the method Apple itself recommends, and it's what most people use.
Key Takeaways
- Dragging an app to Trash is the standard way to delete it, and you should empty the Trash afterward to reclaim the space.
- Some apps leave behind support files after deletion, but these typically use very little space and won't slow down your Mac.
- If an app won't move to Trash, restart your Mac first — the app may still be running in the background.
- Third-party uninstaller apps can remove support files, but they're optional unless you're trying to free up significant space.
- Built-in apps like Mail and Safari cannot be deleted, though you can hide them from view.
When an app won't delete and what to do
If you try to drag an app to Trash and get a message saying you don't have permission, or the app straightforward won't move, the app is likely still running. Close it first: click the app's name in the menu bar at the top of your screen, then select Quit [App Name]. If you don't see the app in the menu bar, open Activity Monitor (search for it using Spotlight by pressing Command + Space), find the app in the list, click it, then click the X button labeled Force Quit.
After you've closed the app completely, try dragging it to Trash again. This almost always works. If it still doesn't, restart your Mac — sometimes background processes prevent deletion, and a restart clears them.
A few apps come with their own uninstaller. If the app's folder contains an Uninstall icon, double-click it and follow the prompts. This removes the app and its support files in one step. Check the Applications folder or the app's own folder to see if one exists.
Removing leftover files after deletion
When you delete an app by dragging it to Trash, macOS leaves behind support files — things like preferences, caches, and saved data. These files are stored in hidden folders that Finder doesn't show by default. For most apps, these leftovers are small enough that you won't notice them, and they won't affect your Mac's speed.
If you want to remove these files, you have two options. The first is to find and delete them manually. Press Command + Shift + Period (the period key) in Finder to show hidden files. Navigate to your Library folder (in your home directory), then look in the Caches, Preferences, and process Support folders for files or folders with the app's name. Delete any you find. This method takes time but costs nothing.
The second option is to use a third-party uninstaller app like AppCleaner or CleanMyMac. These apps scan your Mac, find all the files related to an app, and delete them together. They're not necessary for most people, but they're useful if you're trying to free up space or if you delete apps frequently.
Apps you cannot delete from your Mac
Apple's built-in apps — Mail, Safari, Calendar, Contacts, Reminders, Notes, Maps, Stocks, and a few others — cannot be deleted. If you try to drag one to Trash, nothing will happen. These apps are part of macOS itself and are required for the system to function properly.
If you don't use one of these apps, you can hide it instead. Right-click the app in Applications, select Options, then check Hide. The app will no longer appear in Launchpad or when you browse Applications, though it's still on your Mac. You can unhide it the same way if you change your mind.
Checking how much space an app uses
Before you delete an app, you might want to know how much space it's taking up. Open System Settings, click General, then select Storage. Wait a few seconds for the list to load. You'll see every app on your Mac with its size listed next to it. Click an app to see more details, including when you last used it.
This view helps you identify apps you haven't opened in months and decide which ones are worth keeping. Apps vary widely in size — some take up less than 10 MB, while others (like video editors or games) can use several gigabytes. If you're running low on space, deleting large apps you don't use is one of the fastest ways to free it up.
What happens to your data when you delete an app
Deleting an app does not delete the files you created with it. If you used an app to write a document, edit a photo, or create a spreadsheet, that file remains on your Mac in whatever folder you saved it to. You can still open it with a different app, or reinstall the original app later and open it again.
The only data that disappears is the app's own settings and preferences — things like the window size, your login information, or custom configurations you set up. If you reinstall the app, it will start with default settings, and you'll need to set it up again.
Reinstalling an app after deletion
If you delete an app and later decide you want it back, you can reinstall it. For apps from the App Store, open the App Store, search for the app by name, and click the Get button (it may say Install or Redownload depending on whether you've purchased it before). For apps you downloaded from a website, go back to that website and read the installer again.
Your files created with that app are still on your Mac and will open normally once you reinstall it. Your preferences and settings won't return — the app will start fresh — but your actual work is safe.
Frequently Asked Questions
Does deleting an app from my Mac free up space when ready?
Yes, but only after you empty the Trash. When you drag an app to Trash, it's still on your Mac taking up space. Right-click the Trash icon in your dock and select Empty Trash to permanently remove it and reclaim the space. Until you empty the Trash, you can still recover the app by dragging it back out.
Will deleting an app slow down my Mac?
No. Unused apps don't slow down your Mac just by existing. They only use space on your hard drive. Deleting them won't make your Mac faster unless your drive is almost full — when your drive is nearly full, your Mac does slow down. In that case, deleting large unused apps can help.
Can I delete an app while it's running?
Not directly — you'll get an error message. Close the app first by clicking its name in the menu bar and selecting Quit, or by using Force Quit in Activity Monitor. Once it's closed, you can drag it to Trash without any problem.
What's the difference between dragging to Trash and using an uninstaller app?
Dragging to Trash removes the app itself but leaves behind small support files in hidden folders. Uninstaller apps find and remove those support files too. For most people, dragging to Trash is enough. Uninstaller apps are mainly useful if you delete many apps and want to clean up every trace.
If I delete an app, will I lose my documents made with it?
No. Your documents are separate files saved in your folders. Deleting the app doesn't touch them. You can still open those documents with a different app, or reinstall the original app and open them again.
