#4 Unified notifications for apps on the web:

The unified notification is another new feature in Apple OS Mountain Lion. These add-ons continuously notify the users about updations in websites, social updates and new Apple services like software updates. Another feature is that these notifications can be customized into several styles. One more notable feature is that the OS X Mountain Lion can automatically disable all the notifications when users are busy with presentations or when streaming live videos.

#5 Browser tabs across the cloud:

One of the most highlighted features in OS X Mountain Lion is the characteristic of swapping browser tabs from one machine to another. Apple’s latest browser, Safari 6.0 has an unique feature of transporting the list of recent and most used tabs from one Mac machine to another, respective of the same Apple ID. Apple is also thinking to integrate these features into their upcoming iOS 6, which is ready to be launched later this year.
