Overview
- Apple released iOS 27.0.1 on Monday to fix a bug that could cause iPhone 18 Pro and 18 Pro Max devices to restart when Face ID failed to authenticate.
- The update also corrects a camera color artifact seen at 2x on a small number of 18 Pro units and fixes a touchscreen freeze that could occur when Notification Center and Control Center were opened together.
- Apple simultaneously pushed matching 27.0.1 updates for iPadOS, macOS and visionOS and issued iOS/iPadOS 26.7.1 and related macOS patches that close a CoreGraphics out‑of‑bounds write used in a targeted exploit.
- The Face ID problem appeared after iOS 27 and the iPhone 18 Pro launch and Apple has said the issue can be fixed in software even though the new models use an under‑display infrared Face ID sensor.
- Users can install the update over the air or via IPSW, and people still on iOS 26 are urged to install 26.7.1 promptly because the patched CoreGraphics flaw was exploited in sophisticated, targeted attacks.
