Sun Apr 27 09:40:00 UTC 2025: ## Apple Stops Allowing Downgrades to iOS 18.4

**CUPERTINO, CA** — Apple has ceased signing iOS 18.4, preventing users from downgrading to that version after installing the more recent iOS 18.4.1 update. This is standard practice for Apple, ensuring users benefit from the latest security patches and bug fixes.

iOS 18.4.1 includes crucial security updates, addressing vulnerabilities, including one actively exploited by attackers, and resolving issues with wireless CarPlay functionality. Apple urges all users to update to iOS 18.4.1 immediately. The move to stop signing iOS 18.4 is a server-side change that prevents installation of the older software version.

This is not the only Apple news, as the company is also preparing for its annual developer conference, where it is expected to unveil iOS 19, macOS 16 and other updates. Further details on new iPhone models, including a potential “Air” or “Slim” model replacing the Plus model, were also discussed.
