Apple Releases iOS 27.0.1 to Fix Face ID Failures and Other Post‑Launch Bugs

The small update restores device stability for iPhone 18 Pro models and is paired with separate security patches for older systems to close an actively exploited flaw.

Overview

  • Apple rolled out iOS 27.0.1 on Monday, Sept. 28, 2026, and the update is available over the air in Settings → General → Software Update or via IPSW files for manual install.
  • The release fixes a Face ID–related fault on iPhone 18 Pro and 18 Pro Max that could cause authentication to fail, trigger a “Face ID is Not Available” message, freeze the device, or lead to unexpected restarts.
  • iOS 27.0.1 also resolves a touchscreen freeze that could occur when Notification Center and Control Center are opened at the same time and corrects a rare color artifact that appeared in some 2x photos on a small number of iPhone 18 Pro models.
  • Apple issued matching 27.0.1 bug‑fix builds for iPadOS, macOS, and visionOS as part of typical post‑release granular updates; published build numbers include iOS/iPadOS 27.0.1 (24A446) and macOS 27.0.1 (26A434).
  • Separately, Apple released iOS 26.7.1 and related 26.x updates to patch a CoreGraphics out‑of‑bounds write that the company says was used in targeted attacks, and users who have not moved to iOS 27 are urged to install those security fixes immediately.
