Apple just confirmed its earning report that it will launch the new OS X Mountain Lion tomorrow. This new version of the Apple's Flagship operating system will have various new features.
With greater iCloud integration, Messages, and social sharing, along with a brand new Notification Center, Apple continues the "iOS-ification" of its desktop operating system to bring it closer in line with its mobile cousins.
The upgrade will be just $19.99 for older Mac's and for the recently purchased ones it will be free. It will be available for download on the Mac store by tomorrow.
