Can u run GW on a mac?

Can u run gw on a mac my friend wants to know

Not on OSX. You'll need to use bootcamp and install window in order to play.

To clarify:

If it's one of the new Intel based Macs, you can run Windows natively using bootcamp.

If it's an older Mac you have to use an emulator to run Windows.

GW doesn't run in OSX.

If you search here you'll find several other threads about this, with more info.

YOU DON'T NEED BOOTCAMP.
Bootcamp is nice, but running it on a Laptop is brutal for heat dissipation.

You CAN Run Guild Wars on the MAC OS, but you require software Emulation.
"Wine", an application made for Linux, to allow Emulation of dll and exe functionality enables this. What you want to look for is a Mac OS X product called Crossover Games.

It'll cost a little extra, but you won't need to boot out of OS X to play GW.
It runs flawlessly, and by that I mean it runs faster in Crossover than it does when I reboot to Windows.
