Now that I've had my cup of snark, though, Intel Mac users beware: this one almost uniformly requires a T2 chip, the Apple A10 derivative used as a security controller in the last generation of Intel Macs, and even at least one Mac that does have one isn't supported (the 2018 MacBook Air, presumably because of its lower-powered CPU-GPU, which is likely why the more powerful 2019 iMac without one is supported, albeit incompletely). It would not be a stretch to conclude that this is the final macOS for Intel Macs, though Rosetta 2's integration to support x86_64 in VMs means Intel Mac software will likely stay supported on Apple silicon for awhile. But that shouldn't be particularly surprising. What I did find a little more ominous is that only the 2020 MacBook Air and up is supported in their price segment, and since those Macs are about four years old now, it's possible some M1 Macs might not make the jump to macOS 16 either — whatever Apple ends up calling it.
