Context: this is a legit screenshot I took on my workplace around 1.5 years ago. Hopefully it’s been patched by now? Completely ridiculous behavior

    I can’t remember which model it was, but wasn’t there a MacBook Pro that had 4 USB-C ports, only two of which supported Thunderbolt? Want to connect your monitor to the right side of the machine? Well… tough shit, I guess.

      That’s especially weird considering “pure” USB-C can support 4K/144Hz/HDR with DSC. I guess they just aren’t connected to the M1/M2 GPU.

      As far as I’m aware, all the MacBook Pros with 4 USB C ports, both the 13 and 15/16inch from 2016 until the Apple Silicon ones arrived, were all Thunderbolt certified. I also remember in a few of the teardowns from iFixit that those devices also has one Thunderbolt controller per side.

    • No, I believe it had to do with charging. Charging a Macbook through the wrong part caused some kind of chip to misbehave (overheat, perhaps?) and it would cause issues for the nearby port. You couldn’t charge it quickly through that port either.

      “Luckily”, the early ARM Macbooks couldn’t drive more than a single screen anyway (Apple’s I/O die just couldn’t handle two of their own extreme res screens so they disabled the feature, Linux on the same machine could run two normal screens just fine), so you weren’t able to run into too much trouble with it.
