Yep, that’s the problem 😭 If Apple just finished their driver then it would work.
I suspect they’re protecting Thunderbolt hub manufacturers and DisplayLink, as Apple don’t sell a daisy-chainable Thunderbolt monitor or their own hub/docking station so I can’t see any other reason not to just implement it.
I suspect that this is a feature, or at least a partner-related market decision, rather than a bug, and I suspect the most you’ll be able to say is “the weather is nice today” or “thank you for sharing this”, buuuut…
With a full implementation of DisplayPort 1.2 MST it should be possible to output to two independent (non-mirrored) monitors over a single USB-C port. This can be via an MST hub/dongle or using monitors that support DisplayPort MST daisy chaining. This is a core part of the spec to the point that my Steam Deck supports this.
macOS, however, will treat MST displays as targets for mirroring instead of separate displays. The only way to have an elegant “one wire” experience with a MacBook is to use a much more expensive Thunderbolt dock or a dock that uses a DisplayLink chipset which requires a driver to be installed (as DisplayLink are a company unrelated to DisplayPort).
It’s worth noting that macOS does support MST in the form of two video streams for one very high-resolution monitor, which is kind of interesting.
I’d love it if we could use MST docks/hubs/splitters with macOS rather than either needing expensive third-party peripherals or plugging multiple wires into our MacBooks. Especially because most office setups I’ve seen recently use MST hubs if they offer dual monitors!
Thanks for reading this far, and more importantly thank you for soliciting feedback in this forum and manner. Best of luck!
I try to buy my Mum interesting books for her birthday and Christmas and she always wonders how I find such gems so consistently. My secret - it’s comments like this on Lemmy or the other place, back before the great migration. So thank you - this is going straight on the list! She’ll love it 😊
I hope that you eventually build Linux and Mac clients, as personally my Steam Deck has replaced my Windows gaming PC and I’m not convinced that I’ll ever go back to Windows at this point.
A few dozen hydrogen bombs each? Sir, this is Europe! We won’t have such uncivilised weapons that could be used for discriminatory purposes in our beautiful continent.
No, the only solution is for every country in the EU, NATO, or bordering Russia to be equipped with a Project Sundial device. It’s the only way to preserve European unity.
Get the official dock - it just works. Don't bother with the aftermarket docks. I started with a JSAUX one and it was flaky. Since upgrading to the Valve one everything has been perfect.
The Dbrand Killswitch case is great if you’re taking your deck places and need to minimise packing volume. Adds weight, but it’s rock solid.
I am suffering for a surfeit of brains and would be interested to learn more on this subject. Do you have any references that I could examine, perchance?
I know just the man for the job…
