It appears as though Apple’s latest operating system, OS X 10.9, is primed to make its debut at the World Wide Developers Conference this summer. Inside sources at 9to5mac suggest that the new OS, codenamed “cabernet,” is targeted towards the “power-user.”

If the rumors are true, Apple has shifted away from drastic overhaul upgrades (think OS X Mountain Lion and Leopard) to focusing more on the functions that help make iOS so popular among mobile devices. The big changes are likely to come in terms of multitasking.

9to5mac’s inside sources hint that the 10.9 will allow for the ability to keep multiple full-screen apps open on multiple monitors. There may also be changes in web-browsing and searches, with little revisions to app-based functions like Messages, Notes/Reminders, and Game Center. A latest version of Safari will be available on the 10.9 with updates in page-loading, and general speed and efficiency.

There may also be changes to Apple’s Finder application with the possible inclusion of “tags and tabbed browsing modes. Those additions are notable as many pro-users have relied on third-party solutions and hacks to enable these features.” Outside of these core changes, there are likely to be few updates to other UI features.

The release date is far from set in stone, with many speculating that Apple will unleash the 10.9 at the WWDC in June. Some rumors suggest that some of Apple’s engineers working on the new iOS 7 were taken directly from that team to work on the 10.9, while others say that the 10.9 might be delayed because engineers were taken from that team to work on iOS 7. Whichever ends up being true, there’s no denying the fact that some OS X 10.9 ideas and innovations will mingle with those of the iOS 7, giving more credence to the idea that the 10.9 will more likely resemble the iOS instead of traditional operating systems like Leopard or Mountain Lion.
