Leading digital distribution platform Steam finally made its way to the Mac on May 12, with around 50 launch games. The Mac Steam library now includes 96 titles, including newly released ports of Half-Life 2, Torchlight, and Portal. Check out the MacScene community’s reaction here, here, and here, in addition to a Portal-specific thread here.

As proof of a drastically changing tech landscape, Apple’s market capitalisation surpassed that of Microsoft last week, making it the largest technology company in the world. This marks one of the most incredible turnarounds in any company’s history, with Apple having been all but dead back in 1997, when Steve Jobs returned as CEO. Don’t celebrate too soon, though, because the happy folks at Microsoft are still way ahead on revenue.

In exciting news for Amiga fans, a new emulator called PUAE has been released. PUAE merges Richard Drummond’s E-UAE 0.8.29 with the latest version of WinUAE, and is available for Unix-based platforms. You can download the latest version from here, or check out Ultimate Amiga for more information.

A Mac-native version of GameBase64 Browser has been released. GameBase64 is a database of over 20000 Commodore 64 games, with detailed information and screenshots for each game. Setting up is not exactly intuitive if you do not already have the database file -- you’ll need to drag a folder (any folder) to the application, then it will tell you that the folder contains no valid database file. It will then allow you to download the database file from within the application. You can get screenshots and sounds packs here. It offers the ability to launch games in your C64 emulator of choice, but I couldn’t seem to get that feature working. Despite this strange configuration problem, it’s very impressive, so be sure to check it out (provided you have Snow Leopard installed).

A new version of the open-source IA-32 (x86) emulator Bochs was released on April 25. Release 2.4.5 implements X2APIC and Intel VMx2 extensions, fixes some CPU emulation bugs, reworks the configuration options, and more. Check the changelog for full details.

Those of you desperate for Steam on the Mac will have to wait just a little longer, with Valve announcing that it will be released on May 12. No word yet on what games will be available at launch, although you can be sure a few of Valve’s titles will be there.

More updates after the break.
