Apple released a new build of OS X 10.8.2 to developers on Wednesday just one week after seeding the previous build. The build number comes in at 12C43, and developers are asked to focus specifically on the Power Nap feature.
Apple’s rapid release of 10.8.2 builds suggests that they are planning to release the update soon. OS X 10.8.2 includes full support for iOS 6 features, such as Facebook integration and the ability to merge your phone number with your iMessage ID.
The update will likely be released close to Apple’s iPhone media event next week, alongside the golden master build of iOS 6.
