Running Windows Programs Or Games On My Mac

hi
i have been searching around for crossover apps on the mac, so i can run some games and apps on my mac. (i really want WINDOWS LIVE MESSENGER) i have only been able to find Crossover, which doesn't surport windows live . is there any other crossover programs around???
plz help

Crossover is the commercial implementation of WINE. You could try WINE for OS X. It's more cutting edge and supposedly runs some apps that Crossover doesn't. But... it's also more prone to apps breaking with subsequent releases. And it's not as polished as Crossover is. See link below for more info.

That aside, there's no other alternative I know of short of using a virtualization app like Parallels or VMWare.

Actually, there's a Mac version of Windows Live Messenger. I use it.

Office 2008 has Microsoft Messenger

Here's the official Microsoft version of Messenger:

Microsoft Messenger for Mac: Connect Instantly Online| Mactopia

But I highly recommend aMSN, which is an open source variant. The OS X version has more functionality than the Microsoft version:

aMSN - Opening your communication

Additionally, I highly recommend Adium, which is an Instant Messanging client that supports all of the major instant messaging protocols:
