Steam is available for Mac users today, extending one of PC gaming's best online services to those gaming on aluminum-clad machines from Apple.
"Steam has been a service exclusively for PC users since we launched it in 2004. For the first time we and our partners are bringing it to another platform," Valve wrote in its news section. "It's been a ton of work, but the Mac is great for the same reason the PC is great - they are both open systems that let gamers and game developers be as close as possible."
Those who have PC games purchased on a PC account will automatically get the rights to the authorized Mac versions when they sign in.
Equally as big is word that Steam and the Source engine are being ported to Linux. First evidence of a Linux port appeared in a beta version for the Mac, and now it's been confirmed, reported Phoronix.
Thanks to Steam, the gaming market for Mac and Linux users just got much, much bigger and better.
