The latest update also resolves an outstanding iCloud syncing problem that seemed to arrive with iOS 26.4, according to several users on an Apple developers forum. Affecting CloudKit, the Apple framework that developers use to enable iCloud syncing in their apps, the glitch prevented changes made on one Apple device from syncing via iCloud to a user's other devices, as described by 9to5Mac. Anyone who bumped into this issue should install the latest update to fix this problem.

With iOS 26.4, Apple tweaked the behavior for Stolen Device Protection so that it is automatically turned on by default. An anti-theft feature that requires facial or fingerprint recognition to make certain changes on your iPhone, Stolen Device Protection was introduced in early 2024 but previously had to be manually enabled.

Apparently, the automatic operation applied only to consumer iPhones. On its iOS 26 page for enterprise users, Apple said that Stolen Device Protection will be automatically enabled on devices that update from iOS 26.4 to iOS 26.4.1. If you do use an iPhone through your employer, you'll want to grab the latest update.

To install iOS/iPadOS 26.4.1, head to Settings, select General, and then tap Software Update. Tap the Update Now button, and enter your passcode. The update will automatically be downloaded and installed. Restart your device, and you'll be set.
