Mac OS X Snow Leopard (10.6), released in August 2009, was the first version of Mac OS X (later macOS) to require a Mac with an Intel processor, ending operating system support for PowerPC Macs three years after the transition was complete.

Mac OS X 10.6 "Snow Leopard" had both 32- and 64-bit kernels, and, on most Macs, used the 32-bit kernel even on 64-bit processors.
