How do I completely uninstall applications on a mac?

Please be noted. A simple right-click action like "Move to Trash" only removes the main app file from the Applications folder. On macOS, most apps create additional files outside that location, such as preferences, caches, logs, and support files stored in hidden Library folders. These leftover components are not touched when you just move the app to Trash.

Because of this, many apps continue to leave behind data in places like ~/Library/Application Support, ~/Library/Preferences, and ~/Library/Caches. Over time, these remnants can take up storage space, cause conflicts if you reinstall the app, or even keep background services or login items active without you realizing it.

To completely uninstall apps on Mac, you need to manually locate and remove all related files or use a dedicated uninstaller tool that scans the system for leftovers. This ensures the app is fully removed, freeing up space and preventing potential issues down the line.
