Apple Seeds Second Release Candidate Version of macOS Monterey 12.1 to Developers

Apple today seeded the second release candidate version of an upcoming macOS Monterey 12.1 update to developers for testing purposes, with the new software coming a few days the first release candidate and more than a month after the official release of macOS Monterey.

macOS Monterey on MBP Feature
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.

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.

facetime screen sharing
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.

The full release notes for macOS 12.1:

Hope it fixes the Memory Leaks. Control Center is currently running at 31.63 GB of memory like the finely tuned machine it is.

For every Gb of the memory leak, could I at least get 10 emojis?
Haven't seen any new emoji since 2 releases I'm worried ...

thanks for your thoughts everyone, I'm in these forums since quite some time but rarely ever engaged, because most questions are being answered somewhere here ;)

now on the memory leak topic.. I own a 16"MBP M1Pro 32GB 1TB and must say, I really really like this machine, BUT the software/OS is indeed the worst I've witnessed in my last 16years of Apple user experience. don't get me wrong, I still believe they'll manage this at some point, but never have I had such a feeling of "they don't mind" loosing a few customers for now. they'll probably come back. I know creators that are literally not ready to do business right now due to this silly memory leak, in good hopes with this (still) fancy machines.

I'd like to know how many returns Apple will receive during their prolonged refund policy over the holidays. I told myself to wait for the 12.1 to be released. if Lightroom with gpu acceleration on or off is still causing memory outages with my setup, I'll return it. this can't be for a >3,5k€ piece of technology.
