MacBooks with the M1 Pro, M1 Max, and last year’s MacBook Air with the M2 chip have returned to the popular MagSafe charging connector. The cable in its third USB-C and MagSafe 3 version and is supplied as standard with all the mentioned models. Now Apple has released a firmware update for it, which is automatically installed after the laptop is connected to power with this very cable.
About the update with the label 10M1543 we know practically nothing – Apple didn’t send the update via the standard way, so it will run in the background without user intervention and upgrade the cable’s firmware from version 3.1.8 to 3.1.12. Likewise, Apple doesn’t mention the update anywhere on the site. However, we do know that the cable contains several chips in both types of connectors – be it power or control.
The cable is offered by Apple in all the colors of the new MacBook Air: there is also dark ink or star white
So what might such a cable update include? In the first place, of course, bug fixes are offered, which may have been related, for example, to power management or the detection of supported charging protocols. However, Apple may also be preparing for the arrival of new MacBooks and take into account compatibility with these machines in the cable’s firmware. Alternatively, it could have been anything else, such as adjusting the power profiles, when the chips in the cables can interfere with the power management.
Since 2021, when MacBooks with MagSafe 3 began to be sold, no critical error has been reported, which would relate purely to the cable or power supply, to which Apple would now respond with a firmware update.
In the past, Apple similarly released a firmware update for the MagSafe charger for iPhones, as well as for the magnetic cable for charging the Apple Watch. And in the end, the fundamental question is: when will the firmware for the cleaning cloth from Apple arrive?
