Apple ends support for iOS 18.1.1: Downgrading now blocked

Apple has officially stopped signing iOS 18.1.1, meaning users who upgraded to iOS 18.2 can no longer downgrade to the older version. This change follows Apple’s release of iOS 18.2 on December 11, a move aimed at encouraging users to stay on the latest software.

Why Does Apple Stop Signing Old Versions?

Apple typically stops signing older iOS versions about a week or two after a new update is released. This is part of a server-side verification process that blocks users from installing outdated software. The primary goal is to ensure devices stay updated with the latest security improvements and features.

What’s New in iOS 18.2?

While iOS 18.1.1 focused solely on critical security fixes, iOS 18.2 introduced several new Apple Intelligence features for compatible iPhones. These updates improve functionality and enhance the overall user experience.

In addition to iOS 18.1.1, Apple has also stopped signing iOS 17.7.2, signaling the company’s continued push toward ensuring users adopt newer versions.
