Apple is reportedly planning a major overhaul for its OS X 10.10 version, codenamed Syrah, by redesigning the software to a greater extent, and will give it more prominence than iOS 8 at the company’s annual Worldwide Developers Conference in June. This new version of the software will in fact be the company’s most important update to the software since its launch of OS X over a decade ago, 9to5Mac reports. The new version will flaunt a completely revamped design, which is likely to be somewhat similar to the design of the last year’s iOS refresh.

As far as the name of the software goes, the company is codenamed Syrah for internal development however is likely to market with a different name. The company has reportedly looking for trademarks for California landmarks such as Yosemite, Mammoth, and Diablo, and might as well use any of these in the name of the software. Last year Apple changed its policy of naming OS X versions after cats and started naming them after landmarks in California starting with Mavericks.

In terms of design, it is speculated that OS X 10.10 will come with iOS 7-like toggles and interface coupled with sharper window corners, icons, better icons, and more white space than OS X Mavericks. Apple, however, will not bring changes to the Finder, multi-window multitasking, and Mission Control features, to maintain the difference between iOS and OS X.

As far as iOS 8 is concerned, speculations have been made that the software will features new apps like HealthBook, TextEdit, and Preview, as well as boast changes to its voice assistant service Siri, and iCloud. However, the reports also suggest that some of the notable features in the pipeline could instead be released later as a part of iOS 8.1, as the company has moved some of the developers from iOS to work on OS X.

Apple’s WWDC is scheduled for June 2-6.
