Ensure Media Sharing Is Disabled

低レベル 2自動macos

説明

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 Account. 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.
