After launching the first macOS Monterey 12.1 beta at the end of October, Apple has seeded developers with macOS 12.1 beta 3. It arrives as Apple has slated the launch of Universal Control and SharePlay as coming “later this fall” for Mac.

Update 1:07 pm PT: The macOS 12.1 public beta 3 is also now available.


macOS 12.1 beta 3 is appearing now via OTA for developers with build number 21C5039b. You can also download it from Apple’s Developer website if you’re not running the beta yet (full guide here).

With the first macOS 12.1 beta, we saw Apple bring back SharePlay support. However, Universal Control didn’t show up in the first or second beta. We’ll be keeping an eye out to see if the latter arrives with the third beta today.

New features and changes that come with macOS 12 Monterey include a totally redesigned Safari, Shortcuts app arriving on the Mac, a new Focus mode, Quick Notes, AirPlay to Mac

However, Universal Control to seamlessly work across multiple Apple devices and SharePlay are both coming later this fall to the public.

Apple also released the latest macOS Big Sur 11.6.2 beta today alongside the 12.1 beta 3.
