Apple released the new software update macOS 12.1 beta 4. It‘s appearing now via OTA (Over-the-Air) for developers and public testers with build number 21C5045a.

You can also download it from Apple’s Developer website or public beta website.

The new update brings SharePlay to Macs for the first time: a new feature designed to let you watch TV, listen to music or play games over FaceTime.

This is already available in the release versions of iOS 15.1, iPadOS 15.1, and tvOS 15.1.

Cool feature, right?
