Naive question: is the Mac OS or iOS a microkernel? They seem to support http3 in their network foundation librairies and I’m wondering if it’s userland only or more.

MacOS is a hybrid kernel, which has been becoming more microkernel-like over time, and they are aggressively pushing more and more things to userspace. I don't think it will ever be a full microkernel, but it is promising to see that happening there.
Ironic (in the alannis morrisette sense) that Apple has strictly controlled hardware AND OS-level software...if there's anybody out there that can possibly get away with a monolithic kernel in a safe way, it would be them. But Linux...where you have to support practically infinite variations in hardware and the full bazaar of software, that's a dumpster fire waiting to happen.
