Apple develops its own operating system to run on Macs, OS X, the latest version being OS X Mountain Lion (version 10.8). Apple also independently develops computer software titles for its OS X operating system. Much of the software Apple develops is bundled with its computers. An example of this is the consumer-oriented iLife software package that bundles iMovie, iPhoto and GarageBand. For presentation, page layout and word processing, iWork is available, which includes Keynote, Pages, and Numbers. iTunes, QuickTime media player, Safari web browser, and Software Update are available as free downloads for both Mac OS X and Windows.

Apple also offers a range of professional software titles. Their range of server software includes the operating system OS X Server; Apple Remote Desktop, a remote systems management application; and Xsan, a Storage Area Network file system. For the professional creative market, there is Aperture for professional RAW-format photo processing; Final Cut Pro, a video production suite; Logic Pro, a comprehensive music toolkit; and Motion, an advanced effects composition program.

Apple also offers online services with iCloud, which provides cloud storage and syncing for a wide range of data, including email, contacts, calendars, photos and documents. It also offers iOS device backup, and is able to integrate directly with third-party apps for even greater functionality. iCloud is the fourth generation of online services provided by Apple, and was preceded by MobileMe, .Mac and iTools, all which met varying degrees of success.
