Apple is rumoured to be releasing OS X 10.9 codenamed "Cabaret" at WWDC later this Spring. OS X 10.9 which was reportedly delayed so Apple could focus on iOS 7, is rumoured to carry over many features from iOS.
According to 9to5 Mac, those features will include enhancements to the Finder including tags and tabbed browsing modes. The new operating system will also include a new Safari web browser with a redesigned backend for improved page loading, speed, and efficiency. Amongst other features borrowed from iOS will include "Quick App Switching" and a new Multi-Tasking mode.
The addition of tabbed browsing to the Finder will be a boon to many users, who have had to resort to third party apps such as TotalFinder or workarounds that are ineffective at best. The improvements to Safari will be a welcomed addition as the once class leading Safari browser has lost ground in recent years, mainly to Google's Chrome. It's a little more puzzling to understand "Quick App Switching" aas this has been possible for years with the CMD>Tab function. The improvements to bring iOS style Multitasking to OS X 10.9 could be to improve battery life on laptops by actually freezing the apps running in the background and only supplying processing power to the app running in the foreground. This will hopefully be selective as users often have several apps running at one time performing various functions such as photo import, rendering, uploading to Dropbox or ftp.
Another are of improvement needed for OS X 10.9 is multiple full screen apps or spaces. Up until now, Apple's OS only allows one full screen app running at a time, without the ability to access other apps in full-screen mode. In an email to Craig Federigi, Apple's Senior Vice President of Software Engineering, one user lamented this lack of support to which Craig replied "I can't comment on future product plans, but please do know we are absolutely aware of our customers passion on this topic"
Apple has introduced many carry over features from iOS with the current rendition of OS X 10.8 Mountain Lion including iMessage, Notifications and in OS X 10.7, the App Store and iCloud. If past versions are an indicator, expect OS X 10.9 to be shipping Summer 2013. With most of the big cats already used in prior versions, which cat do feel will grace the final version of OS X? Let us know in the comments along with features you would like to see.
