Software history
Defining features
Feature summaries are anchored to the cited Apple first-party source.
iBooks and Maps come to the Mac
Mavericks brought iBooks and Apple Maps to the Mac, extending services that had already become central on iPhone and iPad.
Safari redesign and performance
Safari gained a redesigned Top Sites experience, a new Sidebar for shared links and reading lists, and substantial JavaScript and energy-efficiency improvements.
Better multiple-display support
Menus and Docks became available across displays, windows could span multiple displays more naturally, and an HDTV could act as a full-power display through AirPlay.
Finder Tabs and Tags
Finder Tabs reduced window clutter while Tags made files easier to organize and find across local storage and iCloud.
Efficiency technologies
Timer Coalescing, App Nap and Compressed Memory were introduced to reduce energy use and improve responsiveness under memory pressure.
Archive-product links show the canonical products represented by this project. The full device-name list preserves the broader structured support evidence, including hardware refreshes that do not have their own archive node.
