TIL that MagSafe chargers have firmware, which means they have some sort of processing unit.

I'd wager that all Wireless Chargers Qi or MagSafe have some processing unit on board. Otherwise, they'd have no way to do a "handshake" to determine if they are connected to a phone, how much wattage to supply to the phone, or if someone just placed magnets on them. Creating a potential hazard.

Does an Apple Watch really charge on a MagSafe charger? The newest MagSafe charger only? This would make MagSafe 1000x better! If true???
Nope, unfortunately just an error in the article.

I'm still surprised apple doesn't offer a easier direct way to update on command... Some people have somany devices that a magsafe isn't even worth fidgeting with
I just wish Apple would make a simple settings page listing all the devices linked to your account, and then give me the ability to update them manually.

The current way of doing it is so fragmented, instead of going to the Apple Watch app, Home app for the HomePods or physically going to each Apple TV, a single page for all devices that I can update from one location would be a massive quality of life improvement and that goes for the Apple Pencil and MagSafe charger.

That's cool, but I'm not going to go looking for the version number in settings.

I already have enough version numbers I'm looking out for!

This one I can let silently update without me needing to looking at it.
