StoppedAs of 10 November 2026, from Apple’s published compatibility lists and security updates. Apple doesn’t announce end dates for its fixes: the dates shown are estimates based on its usual pattern, which covers the current version and the two before it. Apple also says only the latest version gets every known fix.
