Update: Here’s a video (thanks commenter)
Steam for Mac went into Beta today. MacStories found some interesting screenshots:
The Mac version of the hugely popular gaming application is very similar to the Windows counterpart, with the same overall colours and look and feel as Valve. Games are accessed in the Library and you can browse the Store.
In early March the company said Portal 2 will be Valve’s first simultaneous release for Mac and Windows when it ships this Holiday season.
“Checking in code produces a PC build and Mac build at the same time, automatically, so the two platforms are perfectly in lock-step,” said Josh Weier, Portal 2 Project Lead.
“We’re always playing a native version on the Mac right alongside the PC. This makes it very easy for us and for anyone using Source to do game development for the Mac.
