Overview
- Apple released iOS 26.5.1 on Monday to address a wired‑charging defect that could prevent iPhone 17 models and iPhone Air from charging when the battery is nearly drained.
- The update is limited to the iPhone 17 family — including iPhone 17, iPhone 17 Pro, and iPhone 17 Pro Max — plus iPhone Air, so other iPhone users will not see the update.
- Users with affected devices can install the patch over the air via Settings > General > Software Update, and Apple will post IPSW firmware for Finder/iTunes installs shortly.
- Apple also issued macOS Tahoe 26.5.1 at the same time to fix unexpected shutdowns on Macs with M5 chips that used certain content‑filtering network extensions, a problem that mainly affected enterprise users.
- The point release is a targeted stability fix while Apple continues beta testing iOS 26.6 and prepares to preview iOS 27 at WWDC on June 8, showing the company is pushing quick, device‑specific fixes ahead of its next major software release.
