"Pure UNIX" is a nebulous term as:
  • Solaris descends from SunOS which in turn descended from 4.1BSD (& 4.2 & 4.3...).
  • Apple's OS X is a hybrid beginning from splicing the FreeBSD userland onto Carnegie-Mellon's Mach kernel.
  • FreeBSD descends from BSD Net/2 & 386BSD.
For more lineage information, see the following:

Likewise note that UNIX itself is a registered trademark when is licensed by the Open Group:

Both Sun & Apple have purchased certification, while the *BSD's have each decided that the fee required for certification is too high. This is the reason you will find the term "Unix-like" used to describe the *BSD family & Linux, although Linux has a completely different heritage by descending from Minix.
