macOS 12.3
macOS 12.3 Monterey has arrived, delivering Universal Control, the long-awaited feature that allows users to transition between Macs and iPads with a single set of input devices.
[…]
For the past several weeks, I’ve had my iPad Pro sitting on my desk in a Twelve South HoverBar Duo stand right next to my Mac’s display. I’ve tried this sort of setup in the past using the ability of Logitech’s MX Keys and MX Master 3 mouse to flip between devices, but it was just cumbersome enough that the setup never stuck.
In contrast, Universal Control makes moving back and forth between my Mac and iPad Pro seamless. It’s not a setup that’s for everyone, but this sort of hybrid Mac-iPad approach is something I’ve done for a long time, just not as efficiently. Now, I have my choice of iPadOS and macOS apps all constantly, and quite literally, at my fingertips. It’s not that I couldn’t accomplish most of the things I do on just one platform without Universal Control. I could, but the difference is that Universal Control gives me the freedom to pick the best tool or the tool I prefer for every task, which is a level of flexibility I love.

Although scrolling works immediately, you can’t control the apps on a platform until you click somewhere inside the destination device’s UI. I thought this would be something I would get used to with time, but after weeks of using Universal Control, I haven’t.

I am shocked to report that two most obvious bugs still haven’t been fixed. The more serious of them is the gaping memory leak in the Finder’s Find command, which has made this major feature next to useless since the first release of Monterey, and was reported to Apple last November (at least).
The other is the inability of the Bluetooth menubar item to report the charge level for Apple wireless keyboards and trackpads when they’re being recharged.
WARNING: it turns on iCloud Drive w/o giving you a choice! Bad Apple.
macOS 12.3 adds four daemons (dtfetchsymbolsd, remotepairingdeviced, cryptexd, nearbyd) and has over 100 changes to existing man pages. Mostly improving them by adding usage examples.

Also it seems that 12.3 kills GPU performance with some cards
I remembered that the Kaleidoscope app team had posted a script that allows me to compare man pages between versions of macOS. They published this back when macOS 12 was released to track the changes of the
plutilcommand line tool. With the help of this tool I determined a few more interested changes in macOS 12, the most interesting of which I will summarize here.
