Nearly every Mac app creates and stores preference files on your Mac. Most of what gets stored is basic settings information. Sometimes those files become corrupted, misplaced, or outdated. Occasionally, that results in an unstable app or broken preferences.
Can you fix preference files? There are two easy ways, both different, both useful.
First, Preference Cleaner is the Mac app that actually finds an apps preference file, records the location, and gives you options to delete (if the file is corrupt, or, if you’re uninstalling the app).
PreferenceCleaner creates a list of apps and their related preference files.
In addition to apps, PreferenceCleaner also checks and stores preferences for your Mac’s System Preferences.
While that may seem like a good way to manage preferences on your Mac, there are other issues to contend with when deleting an app. The preference files can be found, but apps leave other files and folders scattered all over your Mac.
CleanApp is the app I use to get rid of all an app’s files when I delete an app. How? The app actually monitors the apps on your Mac, and notes whenever the app creates or modifies a file.
When it comes time to delete an app, all the app’s associated files get deleted, too, including the wayward preference files.
Drag the app’s icon to CleanApp and it produces a list of all the associated files for that app.
By logging all files created or modified by an app, CleanApp knows where the files are, knows which ones should be deleted, and gives you the option to manage each file.
That makes it a better choice for app and file maintenance than PreferenceCleaner. Of course, the former has a price tag, the latter does not.
