To delete Roblox on a Mac, start by quitting the application. Press `Command + Option + Esc` to open the Force Quit Applications window. Check if Roblox is running, and force quit it if necessary.
Next, open Finder and go to the Applications folder. Locate Roblox and drag it to the Trash bin. This will remove the main application from your system.
After that, empty the Trash to fully delete Roblox. Right-click on the Trash icon and select “Empty Trash” or use the shortcut `Command + Shift + Delete`.
If you have Roblox Studio installed, repeat the steps to remove it as well. Drag it to the Trash and then empty the Trash.
Finally, remove any remaining files. Open the Library folder by going to `~/Library` in Finder. Check the directories `~/Library/Caches`, `~/Library/Logs`, `~/Library/Preferences`, `~/Library/Roblox`, and `~/Library/Saved Application State` for any Roblox files and delete them.
For a simpler process, you can use a third-party uninstaller like App Cleaner & Uninstaller. This will help ensure all Roblox files are removed from your Mac.
