Juli Clover<\/a> (iOS<\/a>\/iPadOS<\/a> release notes, no security<\/a>, enterprise<\/a>, no developer<\/a>):<\/p>\n

According to Apple’s release notes, the software updates contain unspecified “bug fixes.”<\/p>\n<\/blockquote>\n\n

Benjamin Mayo<\/a>:<\/p>\n

\n

While the official release notes were vague, a thread on the developer forums<\/a> indicates it actually fixes a significant bug related to iCloud data syncing.<\/p>\n

Developers had noticed that iPhones running 26.4 would stop receiving iCloud change notifications, which impacted cloud data sync for apps that use CloudKit framework, including Apple’s own Passwords app.<\/p>\n

[…]<\/p>\n

The bug exists on iPadOS 26.4.0 as well, but macOS Tahoe 26.4 was not afflicted by the same issue.<\/p>\n<\/blockquote>\n\n

Adam Engst<\/a>:<\/p>\n

\n

Apple, would it kill you to acknowledge what the bug affected in the release notes? Something like, “Fixes an issue where data synced by iCloud may not appear immediately.”<\/p>\n<\/blockquote>\n\n

Apple<\/a> (MacRumors<\/a>):<\/p>\n

\n

Stolen Device Protection will be automatically enabled on devices that update from iOS 26.4 to iOS 26.4.1.<\/p>\n<\/blockquote>\n\n

Adam Engst<\/a>:<\/p>\n

\n

I tested this explicitly with my update, turning Stolen Device Protection off before I installed, and checking immediately afterward, where it remained off.<\/p>\n<\/blockquote>\n\n

I don’t understand why Apple keeps announcing that it’s doing this and then not actually doing it, or perhaps only doing it for certain users. If, like me, you don’t want Stolen Device Protection, the idea of being opted into it is a bit scary. If you do want it, you may now have a false sense of security unless you check that it was actually enabled.<\/p>\n\n
