Apple seeds new Mac OS X 10.7.2 build, iCloud beta 9 to developers

Apple on Friday supplied developers with a new beta build of Mac OS X 10.7.2, as well as iCloud for Lion beta 9 for testing purposes, just a few days after the last beta builds were issued.

People familiar with the latest beta of Lion 10.7.2 said it is known as build 11C43 and carries no known issues. Developers have reportedly been asked to focus on AirPort, AppKit, GraphicsDrivers, iCal, iChat, the Mac App Store, Mail, Spotlight and Time Machine.

Beta builds of Mac OS X are meant for testing purposes only, and are available to members of the Mac Developer Program. The last major update to Lion came just last week in the form of Mac OS X 10.7.1, packing fixes for Wi-Fi reliability, HDMI output resolutions, and optical audio output.

The last beta build of Mac OS X 10.7.2 was issued to developers this Monday. It came along with iCloud beta 8, and similarly on Friday, the new build of 10.7.2 debuted alongside iCloud for Lion beta 9.

iCloud for OS X Lion beta 9 is an add-on installer for Mac OS X 10.7 Lion that adds in-development iCloud functionality to Macs for developers.

Apple released Lion via the Mac App Store on July 20, quickly selling more than a million copies in 24 hours. According to one analyst, Mac sales got a 26 percent boost in July from Lion's launch and the release of updated MacBook Airs and Mac Minis.
