Legion Defender Mac OS
The macOS operating system is based on Unix, which is sandboxed, meaning it can be very difficult for viruses to do any damage. Bitdefender Antivirus for Mac is the best software for Macs in. Alternatively, Microsoft Defender can be uninstalled from the command line via this single command (administrative credentials required): sudo rm -rf '/Applications/Microsoft Defender ATP.app'.
Legion Defender is a two player game where one player acts as a hacker, and another a victim who must defend against the hacker's attack.
