Meet Mountain Lion: The Latest Mac OS [All Things D]
The most significant feature included in the newest Mac OS X version is full iCloud integration, including "Documents in the Cloud," which will allow documents created on a Mac to sync to the Cloud for use on iOS devices.
Mountain Lion will also have extensive Twitter integration. Numerous applications will allow tweeting directly from the program. It will also include a new feature called the Tweet Sheet, which can be accessed through a new Share menu and will allow for sharing various kinds of media and writing tweets directly from the OS. Facebook integration is, expectedly, absent.
Mountain Lion also includes many popular iOS features, further blurring the lines between the two operating systems. For example, Messages will be added to Mountain Lion to replace iChat and sync with iMessages on other devices. Other iOS features Notification Center, Reminders, Notes, Game Center, and AirPlay will also be included in the Mountain Lion.
In the past Apple has waited 18 to 24 months between OS upgrades, but Lion was released just last summer, so the release schedule appears to be speeding up.
