Apple has officially stopped signing iOS 18.3.2, just one week after the release of iOS 18.4. This means that users who have already updated to iOS 18.4 will no longer be able to downgrade to iOS 18.3.2. The company regularly follows this practice to ensure that users stay on the latest and most secure version of the operating system.
Once Apple stops signing a version of iOS, it becomes impossible to install that version on an iPhone. This restriction applies whether you’re trying to downgrade or restore your device using that specific iOS version.
Why iOS Updates Are Important
The main reason for this policy is to protect users. Newer versions of iOS typically include important security improvements, bug fixes, and performance enhancements. By moving users forward and preventing downgrades, Apple helps to ensure a more secure environment across all devices.
In the case of iOS 18.4, the update includes fixes for more than 60 known vulnerabilities. These changes address potential exploits and system weaknesses, making it the safer choice for all users. If you haven’t installed iOS 18.4 yet, it’s recommended to do so for better protection and stability, notes NIXSolutions.
Keeping You Informed
While some users may prefer staying on earlier versions of iOS for compatibility or personal reasons, Apple’s signing policy doesn’t support this. Once a version is unsigned, it’s no longer considered a valid option for installation. We’ll keep you updated as more iOS releases and signing changes become available, so you always know where things stand.
If you rely on a specific iOS version for certain apps or configurations, staying current with Apple’s signing schedule is essential. As always, timely updates are a key part of keeping your device secure and running smoothly.
