If you happen to be a fan of Valve’s Portal game series but you don’t have a copy of the original Portal for Mac or PC, you’ll be happy to know it is absolutely free on Steam until September 20th. Valve is giving away the title as a part of its “Learn with Portals” educational program, hoping to emphasize the role Portal plays on educating gamers in physics and critical thinking skills.

Developers that are subscribed to Apple’s former MobileMe service are now able to migrate their account over to iCloud through Apple’s new portal. Users will be able to take their Mail, Contacts, and Calendar data with them so they can continue to use iWeb, iDisk, and Photo Gallery until June 30th of next year. Apple also notes, however, that Dashboard widget sync, dock item sync, keychains, signatures, mail account rules, mail preferences, and mail smart boxes are no longer available after migrating.

The point Intel’s Mooly Eden made again and again as he demonstrated the new 2nd Generation Intel Core processor (codenamed “Sandy Beach”) was that it had amazing applications for consumers. The chip, which integrates a graphics processor on the motherboard, was shown side-by-side competing with, and usually out erforming, modern graphics cards.

Sometimes when I’m in the mood to talk specifically about games, I do so over at Gamertell. This week, in my Single Mac Gamer Seeks column, I focus solely on Steam—Valve’s digital distribution platform that’s now available for the Mac. Portal, City of Heroes: Architect Edition, Torchlight and Guns of Icarus already available. With more promised (Portal 2, Half-Life 2, Left for Dead (1 & 2) and Counter-Strike), just how much of an impact will this have on Mac gaming?

As promised, Valve has rolled out the Mac version of Steam, the digital distribution platform for computer gaming. The software is available for immediate download at steamgames.com. Each Wednesday, a new group of games highlighting an area of Steam functionality will be released. This week’s titles show off Steam Play, but the big news is that Valve is making Portal available for free for a limited time.

Steam—Valve’s digital distribution platform for computer gaming—will be arriving on the Macintosh tomorrow, May 12th. Today, Valve announced that on subsequent Wednesdays, additional collections of Mac titles will become available, each designed to highlight specific functionalities of Steam on the Mac. The first collection will demonstrate “Steam Play,” and features the games Portal and Torchlight.

Valve sent out a very brief announcement last night that Steam—their digital distribution platform for computer gaming—will be fogging up your Mac monitor on May 12. That’s it. That’s all they had to say. But isn’t that enough? I mean, you all know it means games such as Portal 2, Half-Life 2, Left for Dead (1 & 2), Portal and Counter-Strike will be hitting the Mac, right?

On Monday, Valve announced that Steam—and the Source engine—will be making their way to the Macintosh platform next month. It’ll take time to see the same amount of titles available for the PC, but there are some popular games planned for the initial launch. Portal 2 will be the first title out of the gates, with Half-Life 2, Left for Dead (1 & 2), Portal and Counter-Strike following closer behind in April.
