=== Mac OS X 10.6 Snow Leopard ===
[[Mac OS X Snow Leopard]] was released on August 28, 2009, the last version to be available on disc. Rather than delivering big changes to the appearance and end user functionality like the previous releases of {{nowrap|Mac OS X}}, the development of Snow Leopard was deliberately focused on "under the hood" changes, increasing the performance, efficiency, and stability of the operating system. For most users, the most noticeable changes were a difference in the disk space that the operating system frees up after a clean installation when compared to [[Mac OS X Leopard|Mac OS X 10.5 Leopard]], a more responsive [[Finder (software)|Finder]] rewritten in [[Cocoa (API)|Cocoa]], faster [[Time Machine (macOS)|Time Machine]] backups, more reliable and user friendly disk ejects, a more powerful version of the Preview application, and a faster [[Safari (web browser)|Safari]] web browser.

An update also introduced support for the [[Mac App Store]], Apple's digital distribution platform for macOS applications and subsequent macOS upgrades.<ref name=":0">{{cite web|url=https://www.cnet.com/home/smart-home/mac-app-store-launches-on-snow-leopard/|title=Mac App Store launches on Snow Leopard|first=Don|last=Reisinger|date=January 6, 2011|publisher=[[CNET]]}}</ref> Snow Leopard only supports Macs with Intel CPUs, requires at least 1 GB of [[Random-access memory|RAM]], and drops default support for applications built for the [[PowerPC]] architecture.
