Apple plans to release its next Mac operating system, OS X 10.9 Mavericks, at the end of October, according to sources with knowledge of the launch plans.
This comes despite claims and speculation that Apple will release OS X Mavericks and iOS 7 in tandem this month. iOS 7 is set to ship alongside the iPhone 5S and iPhone 5C later in September. There has also been chatter about Apple holding the iPad iOS 7 release back until October.
