Mavericks brought iBooks and Maps to the Mac. Finder Tabs grouped windows and Tags let users organize files by category. Multiple-display support gained menus and the Dock on each display, with more flexibility for windowed and full-screen apps.

App Nap reduced the power used by inactive apps, while Timer Coalescing grouped operations to allow the processor to enter lower-power states. Compressed Memory compressed inactive data and restored it when needed. These are features described by Apple, not a promise of identical gains on every Mac. iCloud Keychain and interactive notifications were also new features.

Apple supported the same Macs capable of running Mountain Lion. Specifications required OS X 10.6.8 or later, 2 GB of memory and 8 GB free; the launch offered direct upgrades from Snow Leopard, Lion or Mountain Lion. Some features retained separate requirements. The archive dates 10.9.2 to February 25, 2014 and 10.9.5 to September 17, 2014: a documented selection, not a complete history.
