To uninstall Roblox on a Mac, start by quitting all Roblox processes. Press Command + Option + Esc to open the Force Quit Applications window. If Roblox or Roblox Studio is running, select them and click the Force Quit button.
Next, delete the app. Go to the Applications folder and find Roblox or Roblox Studio. Drag the app to the Trash and then empty the Trash to remove it completely.
After that, remove any related files. Open the Library folder by going to ~/Library in Finder. Delete files from the following directories: ~/Library/Caches, ~/Library/Logs, ~/Library/Preferences, ~/Library/Roblox, and ~/Library/Saved Application State.
If you prefer a simpler method, you can use third-party uninstallers like CleanMyMac X or App Cleaner & Uninstaller. These tools ensure that all related files are removed efficiently.
