Apple blocks iPhone users from downgrading to iOS 18.5

Apple typically stops signing an iOS update within a week or two of releasing a new iOS version. When an update is stopped signing, iPhone users will no longer be able to install it due to server-side software verification checks.

Apple stops signing iOS 18.5, iPhone users no longer have the ability to downgrade

And this time too, just about 1 week after releasing the iOS 18.6 update, "Apple" has officially locked the iOS 18.5 sign. This policy is to encourage iPhone users to upgrade to the new operating system, ensuring security improvements.

iOS 18.6 is a minor update that focuses on fixing a Photos-related bug that could prevent users from sharing memories. In addition, this new version of iOS also patches more than 20 security vulnerabilities.

Experts also recommend that iPhone users should update to iOS 18.6 as soon as possible, especially if they are using previous versions of iOS 18, which have many weaknesses in the security layer.

Thus, when iPhone users have upgraded to the latest iOS 18.6 version, they will no longer be able to downgrade to iOS 18.5.
