World of Warcraft can only run on a PC unless you are a computer genius and use emulators and create virtual hardware.
OSX to me is over simplified. Linux is over complicated. Windows is juuuuuust right. (for me) People just don’t like Windows because it is popular and a lot of people use it. People want to be unique and this drives them away from it.
AND FOR THE LOVE OF GOD DO NOT LISTEN TO THE MAC COMMERSIALS ON THE TV. THEY ARE A LOAD OF BULL!
Wow, so much misinformation.
First, there is a Mac version of World of Warcraft, so if by "computer genius", you mean "able to install a program", then yes.
Second, OS X can actually be as simple as you need it to be (for a lot of novice computer users, this is very important), or as complicated as you want it to be. Its command line interface is pretty much FreeBSD, so it's actually very closely related to the "over complicated" Linux.
Finally, the Mac commercials may not be 100% accurate, but they are effective.
