As expected, Apple has used WWDC to officially reveal their new desktop OS for the first time. The new OS, OS X 10.9 Mavericks, has a few noteworthy changes over its predecessor, including the rumored Finder Tabs. This new feature will allow users to merge multiple windows into a less messy window with multiple navigable tabs. You’ll also be able to copy files between tabs, and swap between tabs to view multiple files and folders.
You’ll also be able to tag files on OSX Mavericks. Tagged files will be able to be searched for within the finder bar, even if the file is not on your hard drive and is only available in iCloud.
There are a few new software features to help improve general usage, including better support for multiple displays, including easy features to plug your new Mac straight into an Apple TV and use that as a second display.
There have also been a lot of optimization features for the new OS X, including new CPU management tools. According to Apple, these tools can help reduce CPU usage by up to 72%. On top of this, a new Safari has been announced to go hand-in-hand with the new OS X.
