Ensure Media Sharing Is Disabled

FaibleNiveau 2Automatiséemacos

Description

Starting with macOS 10.15, Apple has provided a control which permits a user to share Apple-downloaded content on all Apple devices that are signed in with the same Apple ID. This allows users to share downloaded movies, music, or TV shows with other controlled macOS, iOS, and iPadOS devices, as well as photos with Apple TVs. With this capability, guest users can also use media downloaded on the computer. The recommended best practice is not to use the computer as a server, but to utilize Apple's cloud storage in order to download and use content stored there if content stored with Apple is used on multiple devices. https://support.apple.com/guide/mac-help/set-up-media-sharing-on-mac- mchlp13371337/mac Disabling Media Sharing reduces the remote attack surface of the system.
