Overview
- Apple released iOS 27.0.1 on Monday, Sept. 28 to fix three public problems including iPhone 18 Pro and Pro Max devices unexpectedly restarting when Face ID failed to authenticate.
- On the same day Apple also issued iOS/iPadOS/macOS 26.7.1 updates that close a CoreGraphics out‑of‑bounds write that the company says was exploited in targeted, highly sophisticated attacks.
- The Face ID fault involved freezes and reboots that appeared when biometric authentication failed on some new Pro units, and Apple says the problem can be corrected with a software update even though the iPhone 18 Pro family uses an under‑display infrared Face ID sensor for the first time.
- iOS 27.0.1 and parallel 27.0.1 releases for iPadOS, macOS and visionOS are available over the air or via IPSW, the touchscreen freeze fix applies to all iPhones running iOS 27, and Apple recommends users on older 26.x releases install 26.7.1 immediately.
- The quick, granular patches follow iOS 27’s broad rollout two weeks earlier and illustrate how new hardware, new on‑device AI features and real‑world use rapidly surface bugs and prompt fast software remediation.
