Isn’t this just a very early engineering release? Apple may just not yet support all the PCI Express bus stuff required to make GPU hardware work. I’m most curious about whether Thunderbolt will continue being supported given that’s basically an Intel Kool-Aid standard. We may have some very disappointed Pro Display XDR owners soon.

Don't worry, in that case Apple could release a new display with some other connector to replace the old XDR's. Stand connector is kind of old too.

  It isn’t just the display connection. If you have 5k or 8k display, there’s no way Apples SOC GPU is going to compete with an RTX 30x0 or RDNA2 GPU. Not supporting eGPUs sucks, but the coming death of Hackintoshes is kind of worse, and it seems like the Mac ARM era will make any kind of hacking around OSX difficult. no more OSX running in a container with passthrough NVIDIA GPU on your Linux box under qemu

>We may have some very disappointed Pro Display XDR owners soon. It works on Macbook 12" and iPad [1], it works over DisplayPort. [2] Although you do need TB3 for native 6K support. Pro Display XDR requires a GPU capable of supporting DisplayPort 1.4 with Display Stream Compression (DSC) and Forward Error Correction (FEC), or a GPU supporting DisplayPort 1.4 with HBR3 link rate and Thunderbolt Titan Ridge for native 6K resolution. If multiple displays are being used with the same Mac, each display can be configured independently for settings such as reference modes and orientation.

TB3 is an optional part of the USB4 spec. It's very likely that Apple will support USB4/TB3.

  Screwing around with ports is what Apple does best.

Apple has signalled for a couple of years that they’re not really interested in supporting eGPUs, so no real surprise there. But I’d be very surprised if they dropped TB, considering it’s the superior standard at the moment and USB4 is still not done (afaik). I’m sure they know it well enough to make it work even with non-Intel hardware.
