Apple today seeded the third beta of an upcoming macOS Monterey 12.1 update to developers for testing purposes, with the new software coming a week after the second beta and three weeks after the official release of macOS Monterey.


Registered developers can download macOS Monterey 12.1 beta profile through the Apple Developer Center and after the appropriate profile is installed, the beta will be available through the Software Update mechanism in System Preferences. Apple has also seeded a new beta of macOS Big Sur 11.6.2 for those who have not yet updated to Monterey or who can't on an older machine.

macOS Monterey 12.1 brings SharePlay to Macs for the first time. SharePlay is a new feature that's designed to let you watch TV, listen to music, and play games with friends and family members over FaceTime.


SharePlay allows all kinds of apps to work with FaceTime, with content synced for all people who are part of the FaceTime call. You can listen to music with Apple Music and access shared playlists, watch synced TV shows and movies together, work out together, and even share your screen for things like group trip planning or device troubleshooting.

Apple designed SharePlay to work with first-party app options like Apple TV, Apple Fitness+, and Apple Music, but there's also an API for developers so third-party apps can also use SharePlay FaceTime features for games and other experiences.

SharePlay is already available in the release versions of iOS 15.1, iPadOS 15.1, and tvOS 15.1, so the Monterey 12.1 update brings Macs in line with other Apple devices.

How many people are actually going to use all of this SharePlay stuff? I mean, really? It sounds cool, but how many people in their busy lives are really all that bothered about it?

great question. There is an audience for this, but it is minuscule compared to the population that needs a stable, “it just works” operating system.

what’s amazing to me is how many aspects of the os break each release which get no additional functionality.

Hopefully fixes Sms issue where can’t send an SMS message (green) with a photo. Non photo messages for green work fine and blue works fine for everything.

My big issue is getting kernel panics multiple times a day on my new M1. Seems to be when connecting or disconnecting from OWC Thunderbolt Hub. Saw another with same issue on M1 macOS beta using cal digit. Don’t know if it’s Monterrey beta issue or hardware issue specific to my machine or some kind of combination. Was on stable for first week of M1 and don’t think there were any kernel panics.
