Overview
- Apple’s iOS and iPadOS 26.4.1 updates, released Thursday, restore iCloud syncing on iPhones and iPads that fell out of date after 26.4.
- A bug in CloudKit stopped devices from processing incoming iCloud change alerts, which left Notes, shared passwords, and many third‑party apps showing old data.
- Apple acknowledged the issue in its developer forum and asked developers to install 26.4.1 to verify that syncing works again.
- The update also turns on Stolen Device Mode for enterprise‑managed devices, which forces Face ID or Touch ID for sensitive account changes when away from trusted places.
- Apple lists no security fixes or CVE entries for 26.4.1, and reports say macOS 26.4 was not affected by the sync bug.
