Overview
- iOS 27.2.1 was released on Monday, November 9, 2026 as a minor point update that addresses bugs and patches security vulnerabilities for iPhone users.
- Apple issued matching point releases for iPadOS 27.2.1, macOS 27.2.1 and watchOS 27.2.1 that deliver similar fixes and performance tweaks across its device lines.
- Some builds are product specific so owners of hardware like the iPhone Duo, PROLED MacBook Pro, and M6 Macs may see different build numbers for the same nominal update.
- Users can install the updates manually by going to Settings > General > Software Update or rely on automatic updates to apply the changes for them.
- Apple also pushed maintenance updates for older OS branches so devices not on iOS 27 received security patches, and the company continues development with developer betas for iOS 27.3.
