OS X Mavericks release date will be this October according to GottaBeMobile and 9 to 5 Mac, amongst other sources. The Apple desktop OS has already reached its seventh beta, which means it has entered final testing. The newest iteration of Apple’s desktop OS is expected to launch with the new MacBook Pro with Intel Haswell processors.

9 to 5 Mac stated that this delay in the release happened as Apple decided to focus on the development of the iOS7 that has to be released with the next generation of iPhones, the 5S and the 5C. The said devices were released last September 10 at the company’s keynote event. According to the Mac-focused site, once the iOS7 is released this month, Apple can then finish with the OS X Mavericks in time for a launch by the end of October.

GottaBeMobile.com disproved the belief that Apple will be releasing the iOS 7 and OS Mavericks together by pointing out that for the last few years, Apple has been launching their latest OS X versions a day after they get their 4th Quarter earnings call. This is normally around mid-October.

According to GottaBeMobile.com, since Apple waits for their iOS versions to be ready for release with their new iphones, the same must apply to the Macbooks and the OS X. This means that consumers can expect the new MacBook Pros to come out in late October.

The OS X Mavericks will come with better flexibility in Finder, faster Safari web browser and a host of newly developed iBooks apps. With all the beta stages OS X Mavericks has gone through since its official announcement in June at the WWDC, GottaBeMobile.com predicts that the performance to expect will have been worth the wait.

The new MacBook Pro with Retina Display is rumored to support 4K display. The new high-resolution displays are expected by many to be 4x better than standard HD screens.
