I've got almost the same wish list as the OP, so I'll share my experience.
TL;DR: I use a Matias Quiet Pro, full size. It's glorious. Alps switches feel good.
My first mechanical was the DSI SMK-88, a compact tenkeyless… in cherry
black. I found the linear keys suboptimal, but it offers the layout you like, the size you like, and that probably ought to count for a lot.
My next carefully considered keyboard was a Matias Tactile Pro Mk.1. (I also rehabbed a Das Mk.1 but that was a side project) It was great - I loved the layout, loved the softer feeling of the Alps than Cherries, and loved the system hotkeys. I found the "optimizer" secondary and tertiary key printing really nice and really useful - did you know that "alt ;" produces an ellipsis? I didn't either.
The closest to your gold standard is probably the
Matias Laptop Pro. It's a bluetooth mechanical tenkeyless mac keyboard that feels a lot like heavy Browns but is, alas, not backlit - but I asked Matias for something like that, and they said they'd consider it. If you'd be so good as to email them, along with a couple dozen more mac fans, we'll probably get one. But I'd get the one on offer now, it's a really nice board.
