To delete Roblox from your Mac, start by quitting the application. Press Command + Option + Esc to open the Force Quit Applications window. If Roblox is running, force quit it.
Next, remove Roblox from the Applications folder. Open Finder and navigate to the Applications folder. Locate both Roblox and Roblox Studio, then move them to the Trash bin.
Now, you need to remove Roblox files from the Library folder. Open Finder, go to the menu, and select Go → Go to Folder. Type ~/Library
and press Enter. Delete files from directories such as Caches, Logs, Preferences, Roblox, and Saved Application State.
Finally, empty the Trash. Right-click on the Trash icon and select Empty Trash, or use the shortcut Command + Shift + Delete.
For an easier method, consider using a third-party uninstaller like App Cleaner & Uninstaller to simplify the process.
