Apple has stopped signing iOS 26.5 and 26.5.1 following the release of iOS 26.5.2, which includes critical security fixes. This action prevents users from downgrading to the older software versions after addressing significant vulnerabilities tied to potential AI-driven hacking.
Apple has ceased signing for iOS 26.5 and 26.5.1, making it impossible for users to downgrade to these versions from newer releases. This practice is standard for Apple as they ensure that only verified software versions remain available after proving their stability.
The halt in signing coincided with the launch of iOS 26.5.2 on June 29, which was flagged as an important update addressing critical security vulnerabilities. Apple allowed a week for this release to stabilize before cutting off access to its predecessor versions.
The urgency of this update was heightened by risks associated with AI-powered hacking. Apple expedited some fixes planned for the forthcoming iOS 26.6 to enhance user security and respond swiftly to these threats.
The company is currently testing iOS 26.6 beta 4 and iOS 27 beta 3, with general availability of iOS 26.6 expected later this month. Public beta testing for iOS 27 is also set to commence this month.
