OS X Mavericks release date according to rumors will be this October 15. It is expected by many that the new desktop OS by the Cupertino tech giant will be launched with the new MacBook Pros and iPads.

Now that OS Mavericks is on its eight developers’ preview, the new operating system is reported to being tweaked and tested for a final release. Based on recent release dates history, it usually takes less than two months for Apple to release the final version of an OS when it’s seventh and final beta is sent to developers.

Adding to the excitement is the expected simultaneous launch of the OS X Mavericks with Haswell-powered MacBook Pros and the anticipated iPad 5 and iPad Mini 2.

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 and the new high-resolution displays are expected by many to be four times better than standard HD screens.
