Within the market of desktop, laptop and home computers, and by web usage, it is the second most widely used desktop OS, after Microsoft Windows.
The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year.
The X was a prominent part of the operating system’s brand identity and marketing in its early years, but gradually receded in prominence since the release of Snow Leopard in 2009.
After Apple announced that they were switching to Intel CPUs from 2006 onwards, versions were released for 32-bit and 64-bit Intel-based Macs.
