Even before the iOS 15 announcement, 9to5Mac found out that Apple was working on a new way to deliver alternate security updates to iPhone and iPad users.

For some unknown reason, the company has backtracked and is no longer letting users stay on iOS 14 with security updates.

Instead, it has reverted to the traditional method of updates where users are forced to install the latest version of the operating system (which is iOS 15) to get the security improvements.

Previously, iOS 15 was shown as an optional update, while users could just install iOS 14 security patches.

While this could just be a bug, that seems unlikely since the company hasn’t released any other security patches for iOS 14 users since October.

For now, if you want to have the latest security updates on your iPhone or iPad, you’ll have to install iOS 15.
