Mac OS X 10.5 Leopard is an operating system developed and sold by Apple between 2007 and 2009, accompanying Apple’s personal computers. It was officially released on October 26, 2007, priced at $129 for a single license or $199 for a family pack, and was also preinstalled on newly sold computers.

Apple unveiled Mac OS X Leopard as the sixth major release of its advanced operating system. With its release in October, Leopard introduced a plethora of new features, totaling over 300. Some of the key highlights included:

  • Desktop and Dock Enhancements: Leopard introduced a revamped Desktop and Dock featuring Stacks, a convenient way to organize files, and an updated Finder with Cover Flow for easy file browsing and sharing across multiple Macs.
  • Quick Look: A feature allowing rapid previewing of most files without launching an application.
  • Time Machine: A groundbreaking backup and restore utility enabling effortless protection of files and the entire system by allowing users to travel back in time to retrieve lost data.
  • Spaces: A powerful feature facilitating the creation of application groups for seamless switching between tasks.
  • Enhanced iChat and Mail: Improved communication tools for creative interactions among users.

Steve Jobs, Apple’s CEO at the time, hailed Leopard as the best release of Mac OS X, surpassing its predecessor, Tiger, and further solidifying Mac OS X’s reputation as the most advanced and innovative operating system.

Leopard’s redesigned Dock featured Stacks, offering users a convenient solution to manage desktop clutter caused by downloads from browsers and emails. The Finder was overhauled, integrating Cover Flow for intuitive file and application browsing. Additionally, the Sidebar simplified file organization and provided easy access to shared Macs and PCs on a network.
