The process of completely uninstalling an application from a macOS system requires a multi-step approach. Simply moving the application to the Trash is insufficient. It's crucial to identify and remove associated support files and preferences, often located within hidden Library folders, accessible via the Finder's "Go" menu (option-click required). While many applications include their own dedicated uninstallers, leveraging a specialized uninstaller application enhances the completeness of the removal process, ensuring all traces of the application, including cached data and preference files, are eliminated. This practice contributes to system stability and prevents potential conflicts with subsequently installed applications.
Dude, just drag that app to the trash, then empty it. If you wanna be really thorough, check the Library folder (you gotta hold Option while clicking Go in Finder) for any leftover files related to the app. But seriously, dragging to trash is usually enough.
