There have been inquiries from Daniele Nicolodi and Fred Wright about

what's documented for their releases on the Apple website.
If Apple can't be bothered to keep its act together enough to present
a stable and documented API, we can't be bothered to support their
Yes, we used to ship a special accommodation for Apple's non-POSIX
calls in 10.11. At some point it broke. Given what I learned later -
including one rumor that their non-POSIX clock-setting call is a no-op
- I cannot be fscking bothered to figure out *why* it broke.
I consider this entire sorry history a lesson in the wisdom of *not
making exceptions* to our POSIX-baseline policy. Doing that for Apple
was a mistake I don't intend to double down on.
If the 10.12 POSIX clock calls don't work, that's *Apple's* problem.
