Macs use an operating system called Mac OS X which will not run applications written for the Windows operating system. Microsoft produce a Mac OS X version of Word for Apple's Mac computers. There is the option of installing the Windows operating system on a MacBook alongside Mac OS X which allows Windows applications as well as Mac OS X applications to be used.
If you are referring to the operating system then a Mac's default operating system is called Mac OS X. A Mac can be downgraded to run most versions of the Windows operating system from XP to 7.
