Apple has stopped signing several iOS updates released earlier this week, preventing users from installing them even if they still appear in Software Update. The affected versions include iOS 12, iOS 15, iOS 16, and iOS 18.
On Monday, Apple released iOS 18.7.4, iOS 16.7.13, iOS 15.8.6, and iOS 12.5.8 for older iPhone models, along with iPadOS 15.8.6, iPadOS 16.7.3, and iPadOS 18.7.4 for iPad models.
The updates were intended to keep core system services functioning on devices that no longer receive major iOS releases, as well as fix an issue preventing some devices from being able to make emergency calls. Affected iPhone models include the following:
iPhone SE (1st generation)
iPhone SE (2nd generation)
iPhone 5s
iPhone 6 and iPhone 6 Plus
iPhone 6S and iPhone 6S Plus
iPhone 7 and iPhone 7 Plus
iPhone 8 and iPhone 8 Plus
iPhone X
iPhone XS and iPhone XS Max
iPhone XR
iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max
iPhone 12, iPhone 12 mini, iPhone 12 Pro, iPhone 12 Pro Max
The following iPad models are also affected:
iPad mini 2
iPad mini 3
iPad Air
iPad Air 2
iPad mini 4
iPad Pro (9.7-inch)
iPad Pro (12.9-inch) (1st generation)
iPad (5th generation)
iPad (7th generation)
iPad (8th generation)
None of the updates address security vulnerabilities or introduce new features. According to Apple’s release notes for the iOS 12 and iOS 15 updates, the main purpose is to replace an expiring security certificate. Without that replacement, services such as iMessage, FaceTime, and Apple Account sign-in would stop working after January 2027, when the original certificate expires.
Apple has not explained why it stopped signing the updates. In the past, however, the company has prevented installations of newly released iOS versions after discovering bugs or other issues, and then typically re-enabled updates once revised builds become available. We’ll update this article when we learn more.
