OS X Mavericks 10.9 Developer Preview 3 Download Now Available

With Apple currently working on iOS 7 beta and offering bi-weekly beta releases for developers to test, it’s easy to forget that it is not the only operating system that Apple has on the fire. OS X Mavericks 10.9 is also under development inside Apple’s Cupertino HQ, and it too is currently available to developers as part of the company’s Developer Preview program.

Today saw Apple release iOS 7 beta 3 to developers, and OS X Mavericks 10.9 has also seen an update, with Developer Preview 3 now available to download via the Mac App Store for those who are eligible. Weighing in at just over a gigabyte, this update brings with it likely stability and performance improvements just like the latest iOS 7 beta which was released a few hours back. Apple’s own release notes mention some known issues as well as some fixes that have been included in this release, and we’re sure there are more to be found as well.


OS X Mavericks 10.9 is the latest Mac operating system to be announced by the Cupertino company, and is due to be made available to the public later this year. Alongside the usual alterations to the user interface and a spot of spit and polish here and there, Mavericks promises to include some additions that both general and power users will be thankful for.


Vastly improved battery life as well as new iBooks and Maps apps will appeal to just about everyone, whilst power users will be pleased to hear that much improved multi-monitor support is coming in Mavericks, as is a new Finder that features tabbed windows and tags for files. All this adds up to quite the update for OS X 10.9, and Apple will hope to squash as many bugs as is possible via these Developer Preview releases over the coming months.


If Apple is going to continue its current Developer Preview release cadence, then we would expect Preview 4 to land some time two weeks from now, though this being Apple you can never guarantee anything. Here’s hoping Developer Preview 2 hits the spot for now.
