Apple on Friday seeded the Gold Master build of its OS X 10.7 Lion operating system to developers. The build number is 11A511, and the download is available immediately on Apple’s developer site. Barring the discovery of any major issues, the Gold Master code is likely to be unchanged in the release version of Lion, which will launch to the public later this month. Apple announced recently that OS X Lion will be distributed via the Mac App Store rather than using physical media discs, and it will cost just $29.
