Apple's just announced its first-quarter financial results,and while investors and Wall Street may be impressed, I'm more impressed by something else Apple did on Thursday. Just one day after releasingupdates for all of its hardware products, all of which received several security updates, Apple released the first developer previews of iOS 15.4, iPadOS 15.4 and MacOS 12.3 (along with updates forHomePod , Apple TV and Apple Watch ).

The best Macs

Apple's Mac lineup can be confusing as the company transitions from Intel processors to its own Apple Silicon processors. But we're here to help.

After hoping yesterday that after the release of iOS 15.3 as a security-focused update, we'd hopefully see some new features come in iOS 15.4 and the respectable updates for the rest of Apple's hardware, my wishes have come true. 

Specifically, Apple has given developers the first public taste of Universal Control. The feature was first announced last June at WWDC 2021 and promised to give you complete control over your Mac and iPad using a single keyboard and mouse. To be clear, you use the keyboard and mouse that's connected to your Mac, and you're able to move the pointer off the edge of the screen, where it will then show up on your iPad's screen. While it may sound like Sidecar, an already available feature that turns your iPad into a second display for your Mac, Universal Control simply gives you just that -- control over all of your devices from a single spot.

Below you'll find a short video of the feature in use today, in its current beta form, thanks to MacStories' Federico Viticci, who posted it on Twitter. 

Holy wow Universal Control is incredible.
This is me moving between a MacBook Pro, an iPad mini, and an iPad Pro using just the MacBook trackpad and keyboard. It's aware of position, lets you drag files, and supports iPadOS gestures.

As you can see in the clip, Viticci uses his MacBook Pro's trackpad and keyboard. When he moves the pointer off the right side of his screen, it switches over to the iPad Mini where he can type and even use gestures to get around iPadOS. When the cursor moves to the left side of the MacBook Pro's screen, it jumps over to the iPad Pro's display, and he has complete control. Oh, and he's even able to drag and drop files and folders between the devices. 

Dear reader, my mind is blown. 

As someone who regularly moves between aniPad Pro  andMacBook Pro , I can see a few places where Universal Control will streamline the process (editing photos is one) and, hopefully, make me more productive. 

I usually have a pretty hard rule that I'll install etas on myiPhone  andiPad , but I leave my Mac alone just so I have at least one reliable device available. But I just may break that rule to give Universal Control a try. It looks great. Truly. 

Also included in the first developer etas is a new Face ID option for iPhone users that allow you to register your face while wearing a mask, forgoing the need to have an Apple Watch nearby to unlock your phone while wearing a facial covering.

There are also several new emojis, along with the new biliary to copy text that's on a nearby object, like a sign or business card, into the Notes or Reminders app using the camera. 

Are you going to wait until Apple officially releases these updates before giving them a try, or are you tempted to jump on the beta bandwagon? You can sign up for Apple's Public Beta Software Program here; just make sure to create a backup before you do.
