Could coincide with new Macs
Apple is planning to release OS X Mavericks at the end of October, sources claim. There has been some speculation that it could launch in September, following an announcement at Apple's September 10th press event. The company is thought to be focusing most of its software engineering on this month's launch of iOS 7 and new iPhones, however, pushing Mavericks into the October timeframe.
Both OS X Lion and Mountain Lion were released the day after a quarterly results call. Apple should post its Q4 2013 results in late October, which may support the sources' claim.
The company is also due to refresh several Mac lines this fall. Apple sometimes likes to pair OS launches with new Macs; while one or two could be updated on the 10th, Apple may want to avoid drawing attention away from new iPhones, and stagger some or all of the new systems into next month. At the same time, October is when the company is generally expected to reveal new iPads.
