How to Remove App Leftover Files on Mac?
Summary: This post provides two ways to remove app leftover files on Mac to release disk space, including manually deleting the remaining files of uninstalled apps and clearing them with third-party Mac cleaner like iBoysoft DiskGeeker.
For various reasons, you may need to uninstall apps on your Mac such as the app being unwanted, malfunctioned, Mac app icons crossed out due to incompatibility, etc. All but the system applications could be removed from your Mac in any way of the following :
- Click the app icons in Launchpad to make it jiggle, then delete it.
- Locate the App in Finder's Applications folder, right-click, and choose Move to Trash.
- Directly drag-drop the app from Launchpad and Finder to Trash.
- Uninstall an app with its built-in uninstaller.
Do you think that after uninstalling the app, the files created while using the app go away automatically? Totally not. These files are what we called service files, leftovers, remains, or remaining files, including cache files, preferences, error reports, logs, and all other data created by an application as support files. They remain on your Mac after the applications are uninstalled.
Worse, accumulated app leftover files may squeeze the disk space and slow the Mac performance. Therefore, you'd better thoroughly uninstall an app and remove its leftover files from your Mac to free up disk space, speed up your Mac, and so forth.
There are two methods for you to choose from:

Delete app leftover files on Mac manually
When you add an application on your Mac, it creates a lot of support files to make it function well such as the preference files, crash reports, log files, caches, and so forth. These files are scattered around your Mac and are saved in different folders. After the uninstallation, they are still lying there. To manually delete app leftover files, you need first locate them in Finder, including both the Library folder and the Home folder.
- Open Finder on your Mac.
- On the top app menu, click Go and choose Go to Folder.
- Then go to the following folders, one at a time, and press Return.
- Check more leftover files of the deleted app in these folders:
/Library/Address Book Plug-Ins
/Library/Saved Application State
- Drag the associated files of the uninstalled app to Trash.
- Open the Trash, select all the deleted leftover files, and click Empty.
- Go to the Apple menu > System Settings > General > Login Items, and remove the items related to the apps you delete.
Warning: You should not delete the whole folder which contains the support files of other applications, otherwise, it may result in other apps not running. For the unsure file, just leave it alone.
