64-bit in the context of "Mac OS X Leopard"

The Nintendo 64 (N64) is a home video game console developed and marketed by Nintendo. It was released in Japan on June 23, 1996, in North America on September 29, 1996, in Europe and Australia on March 1, 1997. As the successor to the Super Nintendo Entertainment System (SNES), the N64 was the last major home console to use ROM cartridges as its primary storage medium. As a fifth-generation console, the Nintendo 64 primarily competed with Sony's PlayStation and the Sega Saturn.

Development of the N64 began in 1993 in collaboration with Silicon Graphics, initially codenamed Project Reality and later tested as the Ultra 64 arcade platform. The console was named for its 64-bit CPU. Although its design was largely finalized by mid-1995, the console’s release was delayed until 1996 to allow for the completion of the console's launch titles, Super Mario 64, Pilotwings 64, and the Japan-exclusive Saikyō Habu Shōgi.

Mac OS X Tiger (version 10.4) is the 5th major release of macOS, Apple's desktop and server operating system for Mac computers. Tiger was released to the public on April 29, 2005, for US$129.95 as the successor to Mac OS X 10.3 Panther. Included features were a fast searching system called Spotlight, a new version of the Safari web browser, Dashboard, a new 'Unified' theme, and improved support for 64-bit addressing on Power Mac G5s. Tiger also had a number of additional features that Microsoft had spent several years struggling to add to Windows with acceptable performance, such as fast file search and improved graphics processing.

Mac OS X 10.4 Tiger was included with all new Macs, and was also available as an upgrade for existing Mac OS X users, or users of supported pre-Mac OS X systems. The server edition, Mac OS X Server 10.4, was also available for some Macintosh product lines. Six weeks after the official release, Apple had delivered 2 million copies of Tiger, representing 16% of all Mac OS X users. Apple claimed that Tiger was the most successful Apple operating system release in the company's history. On June 11, 2007, at WWDC 2007, Apple's CEO, Steve Jobs, announced that more than 67% of the 22 million Mac OS X users were using Tiger.
