macOS 26.2 adds Infiniband over Thunderbolt support

Been away, just catching up.

I suspect that the next Studio, or perhaps the one after that, will have an option for much faster Ethernet using OSFP or some QSFP variant. 200gbps, probably, but 400 and 100 aren't all that unlikely, and 800 isn't impossible. Look at the nVidia DGX Spark - a significant part of its cost is the inclusion of the ConnectX-7.

I wouldn't have expected it, but it's not impossible that Apple is using nVidia's chip for that purpose right now in their PCC servers. That would explain mellanox drivers, and suggest that we might see that in future Studios. And Pros, if they ever make another, sigh.

However unless you took apart the libmlx5 and can see symbols (or text) confirming that it's mellanox-related, I wouldn't yet take that as proven.
