Following the release of new beta versions on Mondays, Apple released today (8/18) the OS X Yosemite Developer Preview 6 for developers. IOS 8 beta 6, apparently, was left out.
The sixth test version is available for download via the Apple developer portal or the Mac update system itself (within the Mac App Store) as long as developers are running a beta version of the system, of course.
In addition to OS X Yosemite Developer Preview 6 (build 14A329f), Apple has also released Xcode 6 beta 6 (build 6A280e, which features the SDKs for Ma's new operating systems). If relevant news comes up in these new test versions, we will publish everything here on MacMagazine.
