Apple has released a developer preview of the next iteration of the OS X platform, code-named Mountain Lion, which the company says brings more than 100 new features to the operating system.
The new OS, previewed on Thursday, is currently available to download for registered Mac Developer Programme members, but will be made available for other users in "late summer" this year.
New features in OS X 10.8 include an overhauled notifications system, while popular iOS apps such as Notes, Reminders and the Game Center come to Macs for the first time, bringing Apple's mobile and desktop platforms closer together. It also adds Messages to OS X, allowing people to send unlimited messages, including pictures, to other Macs, iPhones or iPads. This replaces the iChat feature found in earlier versions.
