The wait is over. Since Apple presented macOS 12 last year, during WWDC 2021, Universal Control has been one of the most anticipated functions by users. It was, not in vain, one of the star functions of this new generation of Apple’s operating system for its PCs, so much so that it is curious that it was necessary to wait for its third major revision, macOS 12.3, for it to have finally debuted. I clarify, yes, that the planned deadlines have been met even with a little advance, since Apple did not announce for spring.
However, and according to those who have tested the beta of macOS 12.3 Monterey precisely to test Universal Control, The wait was worth it. If you don’t know what this feature is, basically what it does is allow you to use a single input set (keyboard and mouse) to control multiple devices placed in line in front of you. We can consider Universal Control as the evolution of Continuity.
So if, for example, you have an iMac in front of you, a MacBook to its left and an iPad to its right, when you move the mouse pointer to the left to the edge of the screen, if you keep moving the pointer will automatically jump to the MacBook screen, at which point the keyboard and mouse will take over the control of the laptop. And the same to the right, with the iPad screen. Those who have used a PC with two or more monitors and an extended desktop will understand the concept perfectly.
Explained like this, Universal Control seems simple, and it is that by definition it is. However, when comparing systems with more than one monitor, it must be taken into account that in this case we are talking about different devices, not about different screens managed from a single device. And I understand that this complexity is what has caused its debut to be delayed until macOS 12.3, since a fairly complex engineering work is guessed behind it.
macOS 12.3 also brings improvements related to Spatial Audio, its positional sound system, but at this point it is important to clarify that this improvement will only reach systems based on Apple M1, not those that integrate Windows processors. Specifically, the novelty in this regard is that macOS 12 now supports dynamic head tracking for compatible AirPods. In other words, the system will detect the movements of the user’s head, and these will directly affect the way in which the headphones distribute the sound.
Among other new features of macOS 12.3 we find a fairly gender-neutral voice, a wide set of new emojis, the possibility of adding notes to saved passwords and the support of labels with reminders in the operating system’s shortcut function.
