Exactly one month ago, Apple pulled back the kimono revealing its next Mac OS release would be called Mountain Lion upon its debut this summer. It also let eager developers registered in the Mac Developer Program partake in the fun a little early. For the latter camp, Cupertino's back with a second helping today, aptly named Developer Preview 2. No word yet on what's changed in build 12A154q -- a scant twenty-six builds from the 12A128p original -- as the accompanying release notes have yet to be updated. But rest assured we'll circle back with anything of interest when they do.
