“One filecard at a time, it ran whole offices before Office was even a noun.”
“The last cat that spoke PowerPC — 300 changes deep and purring till the end.”
Mac OS X Leopard (version 10.5) arrived on October 26, 2007, as the sixth major release of Apple's desktop and server operating system, succeeding Mac OS X Tiger. It sold for $129 on desktop and $499 for Server, and Apple claimed it packed over 300 changes and enhancements. Fans got a redesigned Dock, Stacks, a semitransparent menu bar, and a Finder with Cover Flow borrowed from iTunes.
Leopard was superseded by Mac OS X Snow Leopard in 2009, but it holds a lasting distinction: it was the final version of macOS to support PowerPC architecture, since Snow Leopard ran solely on Intel Macs. It was also the first Mac OS X to drop the G3 family of PowerPC processors — the end of one era, and the quiet close of another.
