Why cant a program written for the Mac-OS run on a Windows-OS equipped machine?
"OS" stands for "Operating system". This does a lot of technical
stuff, but its most important function is to translate strings of
1s and 0s into something that is actually intelligible to a
user(and does the same in reverse when the user inputs data) Now,
most operating systems have their own "instructions"--made up of
strings of 1s and 0s--that tell them what to do. However, Mac OS
and Windows use different instructions--so if you try to run
instructions for one on the other, the computer has no idea what
you want it to do.
