Completely uninstalling apps from your MacBook
Your MacBook is cluttered with apps you never use. That photo editing software from three years ago. Those games from lockdown. You drag everything to the trash and think: out of sight, out of mind. But it's not that simple.
Every app leaves a trail of hidden files – cache, preferences, support folders. Megabytes of digital junk piling up in your library. The irony? Apple deliberately designed it this way. Just like your AirPods or accessories connect seamlessly to your Mac, apps embed themselves deep within your system.
Convenient for user experience, disastrous for your storage space. One uninstalled app can leave hundreds of megabytes of remnants. In this article, you'll learn not only how to uninstall apps but also how to permanently clean up all that hidden mess. Because only then will you truly reclaim your disk space.

Why correctly uninstalling apps is important
Uninstalling an app from your MacBook seems simple: drag the icon to the trash and you're done. But this method often leaves behind tens to hundreds of megabytes of residual files. These hidden files embed themselves in various system folders and invisibly take up space.
Most apps install extra components in different locations. Think of preference files in the Library folder, cache files for faster performance, and support files with user data. For large programs like Adobe Creative Suite or Microsoft Office, these remnants can add up to gigabytes of wasted space.
The five essential steps for complete uninstallation
Step 1: Completely close the app
Before you start uninstalling, first check if the application is no longer active. Open Activity Monitor via Spotlight (Command + Space) and search for processes of the app in question. If necessary, force quit by clicking on the process and selecting the stop button icon.
Step 2: Use the correct uninstallation method
There are three main methods for uninstalling apps:
-
Via Launchpad (for App Store apps):
- Open Launchpad from your Dock
- Hold down the Option key
- Click the 'x' next to the app to be uninstalled
-
Via Finder (universal method):
- Open a Finder window
- Navigate to the Applications folder
- Drag the app to the trash
- Via its own uninstaller: Some programs come with their own uninstaller. Check the application's folder itself or the developer's website for an uninstaller.
Step 3: Track down hidden files
The library folder contains most of the residual files. To make them visible:
- Open Finder and press Command + Shift + G
- Type ~/Library and press Enter
Check these subfolders:
- Application Support: Contains support files and user data
- Caches: Temporary files for faster operation
- Preferences: Settings and preferences (plist files)
- Logs: Log files of the application
- Containers: Sandbox data of certain apps
- Saved Application State: Recovery data for app crashes
In each folder, search for files with the name of your uninstalled app. Note: be careful when deleting files you are not sure about.
Step 4: Check other locations
In addition to the user library, remnants may also be found in:
- /Library (system-wide): Contains files for all users
- Downloads folder: Installation files you may have saved
- Documents: Project files or templates of the app
Step 5: Empty the trash and restart
After deleting all found files:
- Right-click on the trash
- Select 'Empty Trash'
- Restart your Mac for optimal results
Useful tools for thorough uninstallation
Specialized uninstaller apps
Consider using specialized software for complex uninstalls:
- AppCleaner: Free tool that automatically finds related files
- CleanMyMac X: Paid solution with extensive features
- AppZapper: Simple drag-and-drop uninstallation
These programs automatically scan for all associated files and offer a safe way to remove everything at once.
Terminal commands for advanced users
For technically savvy users, Terminal offers powerful options:
For example, use the following command to search system-wide for files with the specified name:
mdfind -name "[appname]"Common problems and solutions
App will not uninstall
Sometimes an app refuses to be uninstalled. Possible causes:
- System protection: Certain Apple apps cannot be uninstalled
- Active processes: The app is still running in the background
- File permissions: You do not have permission to uninstall
Solution: Start in safe mode (hold Shift during startup) and try again.
Space not freed up after uninstallation
If your disk space does not increase after uninstallation:
- Check if the trash has actually been emptied
- Use Disk Utility to run First Aid
- Check Time Machine local snapshots with:
tmutil listlocalsnapshots /
Tips for future maintenance
Regular cleanup
Make it a habit to monthly:
- Uninstall unused apps
- Clean out cache folders
- Check the Downloads folder
- Locate large files with 'About This Mac' > 'Storage' > 'Manage'
Preventive measures
Prevent unnecessary accumulation:
- Only install apps you truly need
- Where possible, use web versions instead of desktop apps
- Consider portable versions that do not require installation
- Regularly back up before making major changes
Special considerations
Development tools and professional software
When uninstalling development environments such as Xcode, Docker, or virtualization programs, pay extra attention:
- Xcode: Can leave up to 10GB of extra development files
- Docker: Also remove containers and images
- Parallels/VMware: Don't forget the virtual machines
Subscription software
For apps with subscriptions like Adobe Creative Cloud or Microsoft 365:
- First cancel the subscription
- Use the manufacturer's official uninstaller
- Check if license files have been removed
By applying this comprehensive approach, you not only remove the application itself but also all associated files. This results in more available storage space and a faster-running Mac. It takes a little more time than simply dragging to the trash, but the result is a cleaner, more efficient computer without digital clutter.
Conclusion: thorough cleanup pays off
Uninstalling apps from your MacBook turns out to be more work than just dragging them to the trash. Those hidden residual files in Library folders can linger for months or years, silently consuming gigabytes of space.
With the five steps in this article, you can finally truly clean up – from closing processes to tracking down cache files. Whether you choose manual work or a tool like AppCleaner, the most important thing is to be consistent.
Just as you regularly clean your MacBook, your hard drive also deserves periodic maintenance. This keeps your Mac fast and always provides enough space for the things that truly matter.
