Apple ceases iOS 11.4 code signing after release of iOS 11.4.1

Following the release of iOS 11.4.1 earlier in July, Apple on Tuesday stopped signing code for the prior iOS version 11.4 to ensure users are running the latest operating system on their devices.

iOS 11.4


Apple typically ceases code signing for legacy iOS builds roughly one month following the release of a newer version, but in this case the company halted installations of iOS 11.4 only a week after iOS 11.4.1 was pushed out.

The latest iOS 11.4.1 update addresses a number of bugs and patches a few critical security holes. Among the batch of changes was a fix to problematic code that caused some devices to crash when users typed the word "Taiwan" or received a text that containted the Taiwanese flag emoji.

In addition, Apple instated USB Restricted Mode as an option for iPhone and iPad owners. The security feature is designed to disable hardwired USB data connections after a preset period of time in a bid to protect user information from brute force passcode attacks.

The latest iOS revision also fixes AirPod tracking in Find My iPhone and improves the reliability of mail, contact and note sync for Microsoft Exchange. Prior to the update, users complained of battery drain issues that appeared to stem from background data syncing.

Apple regularly ceases code signing to prevent users from installing old, potentially buggy iOS versions following the release of a new OS. The strategy keeps users safe and ensures devices are running the most up-to-date software, thus easing potential compatibility issues with new features and software.

After today, users can only download and install iOS 11.4.1 from Apple's servers.

Apple is working on its next-generation iOS release, iOS 12, and on Tuesday issued the fourth developer beta of the forthcoming operating system to developers for testing. As usual, the update packs in a slew of new features and performance enhancements including new version of first-party apps, a new Measure tool that leverages ARKit to measure objects in 3D space, Siri Shortcuts, Group FaceTime, Memoji and more. Apple is expected to launch iOS 12 alongside a slate of new iPhone models this fall.

    I am tempted to migrate 'backwards' to a most beautiful iPhone 5c I had bought for a family member, not only for simplicity yet also for all the developers that spent time developing great free apps that were then unsupported by an apple 'upgrade' to iOS 11, and orphaned... From an simplistic industrial design standpoint I would rate the 5C as a perfect 10, and yet facing whatever forces drive such obsolescence I would rate Apple by design policy as such an unadulterated fail... When does it all just get a bit stupid? Let the flames begin...

    @Bobolicious..   yes the 5c was a beautiful phone in it's own way..  I have  green one I use as an iPod and with old apps on there.  they ruined how the phone app looked in that older version of iOS with that hard to read white background and tiny font.    Maybe they will come out with a "new" version of that phone style sometime, but you should consider the SE, despite the small screen it's really a lot of power for the price and the one handed use is really awesome in today's world of ever bigger and bigger screens, in other words it feels like a phone and not a tablet when you hold it... LOL...
