Houdini 20.5 Qt 6 Builds - Cool but what about Mac Silicon ??? M2 M3 M4 ???? Vulkan and so on

Vulkan on Mac is done through an emulation layer, MoltenVK. While it's good at what it does, it's not just a drop-in replacement for a proper Vulkan implementation (there are various issues surrounding what it supports which need to be worked around, and the M1-4 GPUs have slightly different requirements). As 20.5 was a short development cycle, we did not have the time to integrate MoltenVK into Houdini for that version.

not only that
I was about to purchase licences for my mac I won(t do it, for instance in cops, before it was slugguish and texture was red and now a big improvment or not only wirefrmae

I'd be amazed if MoltenVK can handle everything you need. Just this past month [github.com]:

"Geometry shaders are awaiting completion of PR #1815, which has stalled due to lack of activity, contributions, and/or prioritized funding support for that feature."

Blender, The Foundry with Nuke 16, Autodesk works for all of us even MacOS users, but here it's worst and worst, and god I love Houdinni but enough is enough

Geometry shaders are a bit of a deprecated feature these days. Tessellation shaders can do almost everything geometry shaders could, and are more GPU friendly. We no longer use them in Vulkan. I'm also not surprised that there's little demand for them, as most Vulkan experts recommend not using them. Vulkan also relegated geometry shaders to be optional (in GL they were mandatory).
