I'm curious why Apple doesn't support this effort: they have done a lot of the work and it won't exactly harm their market share.
I'm curious why you think Apple would support any effort that does not benefit their bottom line?
Users buying Macs to put BSD on them are less likely to buy things in the Mac App Store.
Apple's attitude towards other OSes running on their hardware is less "supportive" and more "barely tolerates". Also as a general rule Apple doesn't contribute much to open source outside of some high profile projects like Swift and Webkit.
Apple is struggling to make MacOS functional, why would they contribute engineering time to another OS?
I still remember when MacOS being based on BSD had the community excited about the future
Interesting article on the failure of Darwin as an open source project: <a href="http://www.synack.net/~bbraun/writing/osfail.html" rel="nofollow">http://www.synack.net/~bbraun/writing/osfail.html</a>
MacOS was never based on BSD. Apple developed the USB drivers for BSP so they could copy it into their OS, but that very different from based on BSD. (It is likely some other parts are copied as well)
Apple publishes the sources to the GPL BSD code they have to but that’s where the support ends.<p>Apple has no interest in assisting a competing operating system.
I would expect if anyone even considered it, they’d immediately reject the idea, as they clearly believe that Apple retains ownership of the computers they “sell” and should control the software you could run on them.
Apple hasn't done any work that would be useful.
Any is a bit too strong. Apple has does (and still does) some useful work with clang/llvm, and a few other tools that BSDs use. However this is indirect at best.
Weird to see this downvoted, because it's totally true. Apple imports FreeBSD's userland periodically but not its kernel/drivers, and thus has nothing to do with how well FreeBSD works on PC hardware: <a href="https://wiki.freebsd.org/Myths#FreeBSD_is_Just_macOS_Without_the_Good_Bits" rel="nofollow">https://wiki.freebsd.org/Myths#FreeBSD_is_Just_macOS_Without...</a>
