It's believed that the current internal codename for the next OS X is 'Syrah', a type of wine, though the internal codename isn't normally the one used for the public release (Mavericks was codenamed 'Cab' according to a screenshot from 9To5Mac).
When will Mac OS X 10.10 launch?
Looking back over the past three versions of OS X suggests that a new version is likely to arrive in 2014.
In 2010, Apple announced OS X 10.7 Lion in October before releasing it to the public in July 2011. In February 2012, OS X 10.8 Mountain was announced before being rolled out in July 2012. Most recently, Apple announced OS X 10.9 Mavericks in June 2013 before making it available to the public in October 2013.
So, while Apple hasn't been consistent in its release dates, it has released a new Mac operating system every consecutive year since 2011.
It's difficult to predict a precise launch date as there has been no evidence to suggest a particular month or date yet, but we have heard that Apple is testing a new OS X, so it does seem that a 2014 release is on the cards.
How much will Mac OS X 10.10 cost?
Apple surprised us this year by making OS X 10.9 Mavericks available for free. See: 7 reasons Apple's free Mavericks was the smartest move it ever made.
We expect Apple to continue to make OS X free in the future, like it does with iOS. Previously, OS X Mountain Lion was just £13.99, though, so even if Apple does decide to put a price tag on the next version, it shouldn't break the bank.
What new features will Mac OS X 10.10 have?
While there's no concrete evidence about the new features expected in the next OS X, taking a look back at some features missing from Mavericks gives us some clues as to what's yet to come.
OS X 10.10: Siri for the Mac
Many expected Apple to make Siri available on the Mac in OS X 10.9. Apple's voice technology was introduced more than two years ago on the iPhone 4S, and then on the iPad, but has yet to make its way onto the Mac. Perhaps OS X 10.10 will be the first operating system to support the voice activated assistant.
OS X 10.10: AirDrop between Mac and iPhone, iPad
AirDrop has been on the Mac since Mountain Lion, and means users can drop files between close-by Macs. With iOS 7, iOS devices got the AirDrop feature too. But unfortunately, Mac and iOS devices cannot AirDrop between each other. We'd love to be able to drop a file from our iPhone to iMac, so we're keeping our fingers crossed for this feature in OS X 10.10.
