The simplest way to remove an app from your MacBook Air
The fastest way to delete an app on MacBook Air 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 disappear completely this way. Some apps leave behind small preference files in hidden folders, but those take up almost no space and won't affect your computer's performance.
If an app won't let you drag it to Trash, or if you want to remove every trace of it including those preference files, you can use the built-in Finder search or a dedicated removal tool. This guide walks you through both methods so you can pick the one that fits your situation.
Key Takeaways
- Dragging an app from Applications to Trash removes it completely for most programs, and this is the method Apple recommends.
- Some apps are locked and won't drag to Trash — right-click the app and select Move to Trash instead.
- Preference files left behind after deletion take up minimal space and won't slow down your MacBook Air.
- If you want to remove preference files too, you can search for them in Finder using the app's name, though this is optional.
Deleting an app by dragging it to Trash
Open Finder by clicking the Finder icon in your dock — it looks like a blue and white face. In the sidebar on the left, click Applications. You'll see a folder full of all the programs installed on your MacBook Air.
Scroll through the list or use the search box in the top right to find the app you want to delete. Click and hold on the app's icon, then drag it down to the Trash icon in your dock. The Trash icon sits at the far right of the dock and looks like a gray trash can. When you drag the app over it, the Trash icon will highlight. Release your mouse or trackpad, and the app moves to Trash.
The app is now gone from your Applications folder and won't open anymore. If you change your mind within a few days, you can open Trash, find the app, right-click it, and select Put Back to restore it to Applications.
What to do if an app won't drag to Trash
Some apps, especially ones that came with your MacBook Air or ones that run in the background, are locked and won't let you drag them. If you try to drag an app and nothing happens, try right-clicking on it instead.
Right-click the app icon and look for an option that says Move to Trash or Delete. Click that option, and the app will move to Trash the same way it would if you'd dragged it. If you still don't see that option, the app may be running — quit it first by clicking the app's name in the menu bar at the top of your screen, then selecting Quit [App Name]. After you quit it, try right-clicking again.
If an app still won't move to Trash after you've quit it, it may be a system app that came with macOS and isn't meant to be removed. You can hide it instead by right-clicking and selecting Options, then Hide. The app will no longer appear in your Applications folder or Launchpad.
Emptying the Trash to permanently delete the app
Moving an app to Trash doesn't permanently erase it yet — it sits in Trash until you empty it. To permanently delete the app, right-click the Trash icon in your dock and select Empty Trash. A confirmation window will appear asking if you're sure. Click Empty Trash again, and the app is gone for good.
You don't have to empty Trash right away. You can leave the app in Trash for days or weeks, and if you decide you want it back, you can still restore it. Only empty Trash when you're certain you won't need the app again.
Removing preference files the app left behind
After you delete an app, it may leave behind small files that store your settings, saved data, or login information. These files take up very little space — usually less than 1 megabyte — and won't slow down your MacBook Air. Most people don't need to remove them.
If you want to find and delete these files anyway, open Finder and press Command + Shift + G. A box will appear asking you to type a path. Type ~/Library/process Support and press Enter. A folder will open showing process preference files. Look for a folder with the app's name or the company that made it, right-click it, and move it to Trash.
You can also search for preference files by opening Finder, clicking the search box at the top right, and typing the app's name. Finder will show you files related to that app scattered across your computer. Be careful to only delete files you recognize as belonging to the app — don't delete anything you're unsure about.
Using a third-party removal tool
Some people use programs like AppCleaner or CleanMyMac to delete apps and their preference files automatically. These tools scan your computer, find all the files related to an app, and remove them in one step. They're not necessary — dragging an app to Trash works fine — but they save time if you delete apps frequently.
If you choose to use a removal tool, read it from the Mac App Store or the developer's website, not from random read sites. Open the tool, select the app you want to remove, and click the delete button. The tool will move the app and its related files to Trash. You still need to empty Trash afterward to permanently erase everything.
Checking if an app is still running before you delete it
Before you delete an app, make sure it's not running in the background. If an app is open, you may not be able to move it to Trash, or you might delete it while it's still doing something important.
To see what apps are currently running, press Command + Space to open Spotlight search, type Activity Monitor, and press Enter. A window will open showing all running programs. Look for the app you want to delete in the list. If it's there, click it and then click the X button in the top left corner to quit it. Close Activity Monitor and try deleting the app again.
Frequently Asked Questions
Will deleting an app free up space on my MacBook Air?
Yes, but usually not much. Most apps take up between 100 megabytes and 1 gigabyte of space. If you delete several apps, you might free up a few gigabytes. Preference files left behind take up almost nothing — usually less than 1 megabyte per app — so removing them won't make a noticeable difference.
Can I delete an app that came with macOS?
Most built-in apps like Mail, Calendar, and Reminders can't be deleted — they're locked to your system. If you don't want to see them, you can hide them by right-clicking the app and selecting Options, then Hide. They'll no longer appear in Launchpad or your Applications folder, but the files stay on your computer.
What happens if I delete an app by mistake?
If you haven't emptied Trash yet, open Trash, find the app, right-click it, and select Put Back. The app will return to your Applications folder. If you've already emptied Trash, you'll need to read the app again from the Mac App Store or the developer's website.
Do I need to restart my MacBook Air after deleting an app?
No. Deleting an app doesn't require a restart. The app will stop working when ready, and you can delete another app or restart whenever you want — there's no special order needed.
Why does my MacBook Air still seem slow after deleting apps?
Deleting apps rarely makes a noticeable difference in speed unless you deleted a very large app or you're extremely low on storage space. If your MacBook Air is still slow, the problem is usually something else — too many browser tabs open, a full hard drive, or a background process using a lot of memory. Check Activity Monitor to see what's using the most resources.
