No. Unix is a operating system that was developed by Bell Labs, now owned by Alcatel-Lucent - which spawned a whole family of Unix-like and Unix-based systems (e.g. the Linux kernel, BSD, and Solaris). Mac OS X is based on and has roots from proprietary modifications of BSD (a "flavor" of Unix-like operating systems) called Darwin.
iTunes is owned by Apple :)

Apple is publicly owned. Their stock price is varying ever day. At the time I am writing this answer, Apple is the highest valued company in the world.
Windows computers are the target of almost every computer virus on the planet because Windows is the most popular type of OS (Operating System). Think about it, if almost 94% of the population who have computers on Earth are using Windows, don't you think hackers and virus writers will take advantage of that and aim at every Windows computer? Apple computers and like you stated, Unix computers, are less vulnerable to virus attacks because the majority of computers are Windows (that's not to say you still can't get a virus if you have Apple or Unix).
Linux is an open source operating system used on computers that would generally run Windows OS. There are many versions of Linux being developed by various interest groups. OSX is a proprietary system owned by Apple that generally runs on Apple computers. There is only one 'current' OSX released by Apple at any one time. OSX is not used on iPhones, iPods, or iPads. Both systems are related to Unix.
The UNIX trademark is owned by The Open Group.
It is a UNIX made.

No, Apple is owned by the shareholders of Apple. YouTube is owned by Google, whose stockholder share share name is : Alphabet A.
iATKOS and other ports of Apple OS X are not designed to support hardware outside of what Apple uses in their Macintosh computers. Adding drivers to an OS X port requires experience with UNIX kernels and depends on the hardware you are running the operating system on. If you are not experienced with UNIX, you definitely should NOT be using an OS X port.
