Wirelessly charging a laptop would waste so much energy. I really hope this isn’t what they’re planning.
I mean...an extra 50 watts maybe? Not great but doesn’t seem like a huge deal.
I'll believe it when I see it. I could believe them getting rid of the touchbar, but bringing back magsafe? I'm sticking with my 2015 MacBook until it's irreparable, and I do like the magsafe port, but is there really any point in going back after moving to USB-C? I think I just like magsafe because it's cool more than that it actually has some sort of superiority over USB-C. I've tripped over the USB-C cable to my w…
I wonder if the "MagSafe" they are talking about is the new magsafe wireless charging on the iphone 12? It would be nice to be able to have a charging pad for my laptop rather than needing to mess with wires at all. Speculation time! I wonder if they will be able to put a magsafe wireless charging spot both under the laptop, and on top next to the trackpad! They could let you charge your iphone from your laptop, and…
I know it's from Kuo, but these leaks don't pass the smell test for me. It makes no sense for them to add the touchbar to the base model 13" MBPs only to remove them from the higher end versions. It makes even less sense to add more ports which aren't USB-C, as the bits about MagSafe and no dongles imply. Further, I don't understand what is meant by "iPhone 12 like" non-curvy design - I have a 2018 MBP 15", and the s…
If I had to pick between USB-C charging and MagSafe, I'd pick MagSafe for accident prevention. The option to use USB-C or MagSafe charging would be a win for everyone.

My favorite part of my touchbar MBP is that it uses USB-C charging. MagSafe is neat, but I don't miss the $80 proprietary charger with a cable that's fixed to the brick and will probably fail if you do anything other than leave it sitting at a desk. Could this be talking about an iPhone 12 style magsafe with a large pad? Not sure how that would work, you'd have to set your computer on top of it to have enough contact…
No law of physics requires a cable with a magnet on one end to not be detachable from the brick on the other end. So while I too do not lament that the cable is no longer affixed to the bricks, I would like Apple to make a magsafe cable that is just not attached that is also not shitty (all those third party USBC attachments have terrible weak magnets that can't even hold themselves in place and I believe can cause power delivery problems).
The touchbar is such a cool piece of technology. I'm sad to see users didn't embrace it as much as they could've. It created a dynamically adapting interface that just opened up so many more possibilities.
It failed at pretty much all it's use cases - it is not available when the laptop is closed, and it's too far when you're at a desk with external keyboard attached even if you don't go clamshell.
It was the ROKR of the Intel->ARM transition - a stalking horse that showed Apple had to go all-in.

I'm not sure that's true. I believe modern wireless chargers are around 75% to 85% efficient. That sounds bad at first, but I believe most ac-dc charging bricks are in the 80% to 90% efficiency range, so it's actually not much worse at all. And if it really is magsafe, the "secret sauce" there is the magnets will align things almost perfectly every time avoiding unaligned charging coils.
There's still a charging brick powering the wireless charger so isn't the 75-85% stacked on top of the 80-90%? That gives you 56-77% efficiency.

The main issue of this is just like with touchbar and similar solutions - power users don't look at the keyboard, so the usefulness will be minimal.
I think HN is a bit unfairly biased against the touchbar, since it serves almost zero purpose for programming work. However, it's quite handy when doing multimedia work with applications that integrate with the touchbar (Logic Pro, Final Cut Pro, Photoshop)
Zoom, for instance, puts the mic, camera, and share desktop buttons right where f1-f3 should go. If they were actual keys it wouldn't matter, but since they're touch sensitive, I have to suddenly be very conscious of where I rest my hands or else risk sending content I do not want to a meeting.

> No, because per the spec, and current technological limitations, there is no way to do a proper connector and logic board.
> It might be possible some day with active electronics, and special electrooptical couplers. But I haven't seen any yet.
Written by Nathan Kolluru. He and Benson Leung were the two guys who did early through technical reviews of USB C cables, later he joined Google as well as a Hardware Engineer, Technical Program Manager. They gave this presentation recently https://www.usb.org/sites/default/files/D1T2-3b%20-%20USB%20... In other words, he actually knows what he is talking about USB C wise, unlike little me :D Interesting writings on USB C hw at https://medium.com/@kolluru.nathan
Edit: please, ffs, stop recommending non specs compliant garbage magnetic connectors. One, you might have very serious ESD issues because now your USB C pins are much more exposed than the normal connector. Two, you might have very serious data integrity issues because those pogo pins do not and can not adhere to the very rigorous specs. I find it absolutely astonishing that people would trust a thousand dollar electronic device on a piece of uncertified cable transmitting 100W and tens of gigabits...
