Apple, today releases the ninth Developer Preview, the build 12F36 for its OSX Mountain Lion 10.8.5. This comes two weeks ahead of the previous seed of the build 12F35 and just a day after Apple seeded the seventh OSX Mavericks developer preview. The update is available as a software update in the Mac App store as well as on the Mac Dev Center for download. However, this update isn’t believed to be as major as its predecessors but will come in handy to the developers anyways. Apple believes its new OSX will be a major improvement over the previous and will greatly improve the OSX’s market share. A new seed for Safari 6.1 is also made available for developers.
