Apple today seeded the first beta of an upcoming macOS Monterey 12.3 update to its public beta testing group, with the new software coming one day after it was provided to developers.

Public beta testers can download the macOS 12.3 Monterey update from the Software Update section of the System Preferences app after installing the proper profile from Apple's beta software website.

Universal Control is the major new feature in macOS Monterey 12.3, and it is designed to allow multiple Macs and iPads to be controlled using a single mouse/trackpad and keyboard. If you have a MacBook Pro and an iPad Pro, for example, both devices can be controlled with the MacBook Pro's trackpad and keyboard or a keyboard attached to the iPad.


iPadOS 15.4 is required for Universal Control on the iPad, and once the updates are installed on your devices, the feature just works as it is automatically enabled.

macOS Monterey also includes new Emoji 14 characters like melting face, biting lip, heart hands, and more, and plus it adds support for updating AirPods with a Mac. There's no official update interface, but your AirPods can receive firmware updates over-the-air when connected to a Mac, similar to how the update process works with an iPhone.

There are some under-the-hood changes too. Apple is removing Python 2 from macOS with macOS 12.3 after support was suspended in January 2020, and Apple is eliminating some kernel extensions used by Dropbox and OneDrive, necessitating software updates for those apps.

Still not appearing on my end, iOS appeared about 10 PT, iPadOS about 10:30, so not freaking out yet.

Don’t run speedtest.net URL uses a lot of memory (GBs) with Safari 15.4 on M1 macs. Use openspeedtest.com instead.
Don’t have safari technology preview installed before updating causes issues with Safari 15.4. It also not working with this beta it seems.

Normal use Safari 15.4 runs fine, except those two instance’s previously discussed.

The installer is about 5GB.

Added to release notes Jan 29
Warning

If your Mac currently has macOS Catalina installed, installing macOS Monterey 12.3 beta or macOS Big Sur 11.6.4 beta on a volume with FileVault enabled might cause a boot loop when attempting to log back into the previous volume. (88163545)

Just tried Universal control with iPad Pro and 16” M1 MacBook Pro. It’s been a while since Apple made my jaw drop, using the trackpad on the iPad is incredible, no discenable lag, entering text on the iPad is now a pleasure using the MacBook Pro keyboard. Seamlessly moving back and forward between the two screens. It’s been worth the wait for this feature.

Does this mean one could control a touch-only iPad OS game with a mouse?

Can you use sidecar and universal control at the same time? And/or switch between them easily?

Universal Control works between my Macbook Air M1 and my iPad Mini Gen 6. The only thing is that I have to put the Mini on the right side of the M1, unless there is a way to manual switch which direction I can use the mouse to switch from screen to screen.

I assume this only works with Apple Silicon and not older Intel based machines. Is that correct?
No
see https://www.macworld.co.uk/how-to/universal-control-3812900/

Compatible Macs include:​

  • MacBook Pro (2016 and later)
  • MacBook (2016 and later)
  • MacBook Air (2018 and later)
  • 21.5in iMac (2017 and later)
  • 27in iMac (2015 and later)
  • 24in iMac
  • iMac Pro
  • Mac mini (2018 and later)
  • Mac Pro (2019)

Compatible iPads include:​

  • iPad Pro
  • iPad Air (3rd generation and later)
  • iPad (6th generation and later)
  • iPad mini (5th generation and later)
This means that if your Mac is from 2015 or earlier it's not a feature you will be able to enjoy (unless you have a 27in iMac from that era).

I jumped in and tried it on my 2018 Macbook Pro and 2020 iPad Pro. It works but it's buggy and lacks a lot of app support. The connection failed several times, leaving the Mac and iPad running normally but no longer seeing each other. A reboot of the iPad fixes that and they see each other again, but rebooting gets tiring. The iPad power button no longer works normally, instead Siri insists on hijacking it, even when Siri is turned off. Video files drag from Mac to Files are very slow to import but then the iPad claims to not know what MKV is and the file isn't there. Further attempts eventually work, but every video I tried so far (100+ MB size) is corrupt when I try opening in VLC.

The Craig Federighi video shows documents dragging from app to app, but the only app this worked with so far was Affinity Designer (running on both sides), and the result was a low-resolution raster image of the vector file including hidden layers. Instead, I had to drag from Affinity Designer on iPad to Mac Finder window, which created a file with a random hex filename, then drag that into Affinity Designer Mac and I got the expected result. I imagine lots of apps will be getting updates to handle this properly and it will eliminate the extra steps.

This is definitely a big step forward for doing real work on an iPad and realizing its hardware potential. It's more complimentary to Mac than ever, rather than being a totally separate platform. But based on the age of the iPad (12 years now?), I feel like we should have had something like Universal Control quite a few years ago.

Thank you so much for your comprehensive answer. I’m not really surprised to see my 2015 MacBook Pro &
Late 2014 Mac Mini not on the list. It’s awesome to see that our iMac Pro is supported!

Update will not load on my 2019 16” MacBook Pro. Download completes and then I receive an error message. I have attempted to install four times now without success. Anyone else having issues installing? Same issue on my daughters 2020 13" M1 MacBook Pro.

Are you already running MacOS 12.2 that also just came out two days ago? You can install that from Mac App Store via searching for macOS Monterey and then install this MacOS 12.3 beta 1.

Did that and it still will not install on both of my Macbook Pro's.
