Apple Releases Updated MagSafe Charger Firmware

[AndrewC89]

My Duo says 256. Not 255 or 258.

Yup, that's the latest version (mine went from 186 to 255).

255? Or 256?

255? Or 256?

I had version 186 and updated to 255. I assumed it was new but it turns out it was released in Feb, my bad.

Yeah, not sure if the new one should be 256, or the same as the regular magsafe, 258.

Looks like 255 is the most current:

My Duo says 256.0.0.0.

My Duo says 256.0.0.0.

Weird, I would have assumed my Duo's firmware would have updated to the most recent version. Maybe (unlike software updates) they have to go in order.

 

[Rafterman]

My Duo says 256.0.0.0.

...Which appears to be the latest for the Duo.

But my regular MagSafe still won't update, for hours now.

Updated my MagSafe charger. Now the noise cancellation on my AirPods no longer works. Thanks, Steve Jobs!

Interesting. I have two Duo chargers.
One shows firmware 186.0.0.0 and the other shows 0.0.2.56
anyone else seen this?

after updating I see the details change to provide extra info - see the before and after shots below.

In the fall of 2022, firmware 255 was released, but I had 247 installed, it seems that magsafe is not updated via iPhone. Connected to the iPad, updated to 258 in 2 minutes.

 

[svish]

Never know what these firmware updates do.

How I can update mine without Mac?

You can try plugging into a USB-C-equipped iPad as well. Good luck to you, don’t worry about it otherwise.

Hopefully it will fix me being tired today.

The fact that there's no way to manually initiate a firmware update is frustrating. I realize these updates likely do little-to-nothing, but who knows since Apple is so secretive about it.

Still on 247. Plugged it into my Mac for two hours. Still 247. Two hours on the iPhone with Wi-Fi. Still 247. Sigh

 

[zakarhino]

They really need to release a longer version of this cable.

 

[zapmymac]

Digs out the “a” to “c” adapter 🤨

 

[gilbertmc]

since i still have a macbook pro without usb c, will it update with an usb adapter? need to test that. still in 247 and left it plugged to a power source and iphone for hours with wifi and bluetooth on and nothing

Plug the MagSafe into a Mac and it will update very fast.

I tried this and it didn’t work yet. Any tips?

 

[JapanApple]

I have 2 Mag safe chargers. both 255.0.0.0 I don't use a Mac mine don't problems update. I need to wait to update both. But my sister has 13 Promax and her mag safe charger is still at 247 and it's connected to a Mac.

 

[seek3r]

What could possibly need updating? It just changes that’s it, what bugs has anyone had with it lol

Could be to support different power profiles from charging bricks, that kind of thing

 

[tagmut]

Does the Apple Watch Magsafe-like fast charge cord have firmware as well?

 

[bigboy29]

Set your phone on it and leave it charging overnight. Might take a while.

We have two MagSafe chargers. iPhone 12 Pro Max and iPhone 13 Pro were on them the whole night and neither updated.

I don't care really but I am somewhat intrigued by how - and if - those things do update without plugging them into a Mac.

 

[lietsche]

Erm… Watches can not be charged using the regular (non-Duo) MagSafe Charger.

Thanks!

I literarily just tried to place my AW somehow on the Magsafe charger to see if it charges and if I missed something 😂
