It’s officially official: Valve will bring its Steam online distribution service and titles from its massive library of hit games to the Mac this April, the company confirmed Monday.

The successful content-delivery service will bring Valve titles like Left 4 Dead and the upcoming Portal 2, as well as games from other publishers, to Apple computers for the first time.

The move was telegraphed last week in a series of teaser posters that mashed characters from Valve games into retro Apple ads. Dan Connors, CEO of Telltale Games, called Apple and Steam a natural fit.

“If there’s anything like iTunes on the PC right now for games, it’s Steam,” Connors said. “So you’ve got two great leaders in digital distribution coming together.”
