MacOS enables each Mac to share folders with other computers on the same network. To share a folder, the user enable and configure the File Sharing service in Sharing settings. MacOS enables the people to connect to shared printers and network printers and print documents to them. MacOS includes a firewall that protects the user MacBook from unauthorized access by other computer son their network or on the Internet.
