Is Apple a Unix or Linux?
Yes, OS X is UNIX. Apple has submitted OS X for certification (and received it,) every version since 10.5. However, versions prior to 10.5 (as with many ‘UNIX-like’ OSes such as many distributions of Linux,) could probably have passed certification had they applied for it.

Why did Apple use BSD instead of Linux?
Apple funded MkLinux a quick and dirty way of running GNU/Linux on POWER, but then they switched to BSD based Darwin and NeXT userland. Apple don’t really like free software so BSD would suit them better. Now that they are on x86 and FreeBSD also targets POWER they could move to FreeBSD if they wanted to.
