How to clean your Mac after apps being removed

Removing App Library Files, Caches, & Preferences

Some applications will also leave behind some preference files and caches, generally these don’t harm anything to leave around, but if you want to delete them it’s just a matter of locating the apps support files and removing those as well. You can typically found these type of files in the following locations.

Application Support files (can be anything from saved states, preferences, caches, temporary files, etc):

~/Library/Application Support/(App Name)

Preferences are stored at:

~/Library/Preferences/(App Name)

Caches are stored in:

~/Library/Caches/(App Name)
