run windows movie maker on a mac

Windows.

There are numerous ways to run Windows on a mac. Some free, some not.

VirtualBox. Boot Camp. Parallels, VMware Fusion, etc.

Go to the BootCamp Support page at:http://www.apple.com/support/bootcamp/ to learn about BootCamp. You will have to use something like BootCamp (free) or Parallels (not free) and then buy a copy of Windows to install under either of those so you can then boot Windows and install/use Move Maker.
