Breaking the recent trend of using feline names for their OS X operating system versions, Apple's forthcoming upgrade will be "Mavericks" - after a California surfing area. From reports from various blogs and insiders, while there will be a few new features the upgrade seems to be concentrating on bringing a new, cleaner aesthetic and a lot of tweaks and polishing. Some of the new features include iCloud keychain, a tabbed Finder and some new Apps. The new Apps should sync across Apple products like the iPhone, and continue steering the desktop and laptop OS X towards the iOS sort of experience. The OS upgrade should be available towards the end of October, probably for around $20, although the cost has not been officially announced yet.
