Apple has Officially Stopped Signing iOS 18.5 & 17.7
Apple has now stopped signing iOS 18.5, now that it publicly released iOS 18.6 on July 29, 2025. Although this seems like a mundane decision, it holds important consequences, especially for power users, developers, and security researchers. For iOS 18.6 owners, downgrading to iOS 18.5 is no longer an option, baked into the way Apple has stopped signing iOS 18.5. Apple’s refusal to sign older versions makes any problem regarding restoring, installing, or downgrading to iOS 18.5 impossible.
