Dragging an app from Applications to Trash doesn't actually delete everything. Apps leave behind preference files, caches, and login items. After years of installing and deleting apps, your Mac is full of orphaned junk.
Here's how to properly delete apps so they don't leave bits behind.
Standard delete – drag to Trash
Open Finder. Click Applications in the sidebar. Find the app. Drag it to the Trash icon in the Dock. Right-click Trash and pick Empty Trash.
The main app binary is gone. But preferences and caches still exist somewhere in your Library. For most apps this is fine. For heavy apps like Adobe products, it leaves a lot behind.
Delete from Launchpad
For apps installed from the App Store, Launchpad has a quick delete option. Open Launchpad. Long-press any app icon until they all start wiggling.
Apps from the App Store show an X in the corner. Click it. Confirm. The app is removed.
Apps you installed manually (downloaded from websites) don't show the X. They have to be deleted from the Applications folder instead.
Find and delete leftover files
After deleting an app, its leftover files live in these locations:
- ~/Library/Application Support/[App Name]
- ~/Library/Caches/[App Name]
- ~/Library/Preferences/com.[company].[app].plist
- ~/Library/Logs/[App Name]
- ~/Library/Containers/[App Name]
Open Finder, press Cmd + Shift + G, paste each path one at a time, look for folders matching the app you deleted, drag them to Trash. Tedious but thorough.
Use AppCleaner to do it automatically
Free app called AppCleaner (from FreeMacSoft) does the leftover hunt for you. Download from freemacsoft.net. Drag an app onto the AppCleaner window. It scans for all associated files.
Review the list it found. Check the boxes for things you want to delete. Click Remove. Everything goes to Trash including the app itself and all leftover files.
Best free option for clean app removal. Worth installing if you uninstall apps regularly.
Apps that can't be deleted normally
Some apps refuse to delete because they're running, locked, or have permissions issues. Common fixes:
- Quit the app first if it's running (Cmd + Q from the app menu)
- Force quit if it's frozen (Cmd + Option + Esc)
- Check Activity Monitor for background processes from that app, kill them
- Restart Mac to clear any stuck file locks
- Some apps need their official uninstaller (Adobe, Microsoft Office)
Adobe apps especially require their Creative Cloud uninstaller. Drag-to-Trash leaves a huge mess.
Delete system apps you don't use
Apple's built-in apps like Stocks, Tips, Garageband, iMovie can be deleted to save space:
- Garageband is about 2 GB
- iMovie is around 3 GB
- iLife and iWork suites add several more GB if installed
For these, drag-to-Trash works fine. They reinstall easily from the App Store if you change your mind.
Bigger cleanup – use Storage Management
Apple's built-in tool. Open Apple menu > About This Mac > Storage > Manage.
Click Applications in the left sidebar. Sort by Size to find the biggest apps. Click any app and hit Delete at the top. Mac asks to confirm.
This deletes the main binary but not the leftover files. Combine with AppCleaner for complete removal.
Apps that protect themselves
Some apps add system-level helpers, login items, or kernel extensions that survive normal deletion. Common offenders:
- VPN apps (NordVPN, ExpressVPN) leave network helpers
- Antivirus apps (McAfee, Norton) install kernel extensions
- Cloud sync apps (Dropbox, OneDrive) have background services
- Screen sharing tools (TeamViewer, AnyDesk)
For these, always run the official uninstaller from the developer's website. Drag-to-Trash plus AppCleaner won't catch everything.
