Early versions of Mac OS were compatible only with Motorola 68000-based Macintosh's.
The first desktop version of OS X (10.0 Cheetah) was released in March 2001 After the first version Apple released  new versions of Mac OS.  OS X 10.1 Puma in September 2001,  OS X 10.2 Jaguar in August 2002,  OS X 10.3 Panther in October 2003, OS X 10.4 Tiger in April 2005, OS X 10.5 Leopard in October 2007, OS X 10.6 Snow Leopard in August 2009, OS X 10.7 Lion in October  2010 and the latest version of  Mac OS is OS X 10.8 Mountain Lion was released on July  2012.
The Mac OS X, operating system has a fresh new look and new behaviors.It has two new state-of-the-art graphics modules. One module handles two-dimensional graphics, and the other renders three dimensional graphics. At the core of Mac OS X is the renowned, rock-solid Unix operating system. From Unix, Mac OS X inherits strength, speed, and resiliency.Apple designed a new user interface for Mac OS X and named it Aqua. Aqua brings semi-transparent menus, controls that look like polished gemstones, shadows for objects such as windows and menus, larger icons with greater detail, and increased use of animation such as buttons that pulsate and controls that change appearance when you move the mouse pointer over them. This list of Aqua features is all visual, but the change is more than skin deep. Aqua also gives Mac OS X a different feel than the predecessors.Mac OS X comes with a whole bunch of applications to do the basics tasks.The Safari web browser, the Mail e-mail client, the iChat messaging tool, the FaceTime videoconferencing utility, the Address Book contacts manager, and the iCal calendar manager are examples for apps.
