Yep, I mentioned that here: bsky.app/profile/alex... There is also the fact that mach ports in XNU do very wonky things with memory sharing, and create shared memory entitlements that raise the question of who owns the memory.

Here is what the Thunderbolt details look like :)

Okay so I had a good idea: DarwinScan, a tool for generating a massive searchable database of a macOS system image for introspection. The goal is to make everything in the system image searchable and viewable, and to cache the shit out of it, and generate diffs between macOS versions.

Reduced it down to just Physical Ports, Thunderbolt, USB, PCIe and MagSafe by default.

It also works for USB! It will show you what is PD.
