Mac OS X Mountain Lion has been a… little bit of a success. It was downloaded three million times in its first four days, making it the series's "most successful release ever" according to Apple. We're pretty sure its impulse-buy £14 price will have helped.
Key new features of the Mac software include a new Notifications Center, AirPlay Mirroring and the Messages application, which lets you send messages to other iOS 5 devices, such as iPads and iPhones. Deeper integration with Apple's portable devices is the order of the day, with notifications in particular giving the desktop software an iOS-like feel.
Critical response to the new software has been generally positive, citing the reasonable price, improved social network integration and the clean look of the notifications system as highlights. There are niggles, but nothing that should hold back anyone thinking of upgrading.
OS X Mountain Lion is available as a 4.4GB download direct from the Mac App Store. The minimum requirements include 8GB of hard disk space, 2GB of RAM and OS X version 10.6.8. According to Apple's own spec requirements, it should work with most MacBooks and iMacs released in 2008 or later - and a few earlier models besides.
