Can Mac OS X 10.6 run Windows games?
Windows games are so called because they require the Windows
operating system to work. Snow Leopard is the latest version of
Apple's Macintosh operating system known as Mac OS X. It is not
Windows and so Windows software, games or otherwise, will not work
with it.
A Mac with an Intel processor can have the Windows operating
system installed on it and can then run Windows software.
Alternatively software such as Wine or Crossover (See links below)
provide an environment where Windows software can be used without
having Windows installed but this can be rather hit and miss and
will not work with all Windows software.
