Apple Software Time Views

Examine Apple software at two scales: major-version progression and a yearly release calendar.

Version progression

From beta to stable

Each track represents a platform major version; markers show the first observed Beta, RC, stable release, and latest update.

This is an observed major-version progression, not an official Apple security-support period. RC belongs to the beta stage, and dates unavailable from Apple are not inferred. Hover, focus, or tap a marker to inspect its version and build. Swipe horizontally to explore the complete timeline.
