Apple has started pushing iPhone users to install the iOS 26.2 update, marking a shift from its usual approach of offering optional updates for older software versions. This time, the company is clear: delaying the update could leave devices exposed to real-world security threats. The warning applies to millions of users globally and affects a wide range of iPhone models that are eligible for iOS 26.
Active security threats behind the update
The primary reason Apple wants users to update to iOS 26.2 is security. The company has confirmed that iPhones are currently being targeted by sophisticated spyware attacks. These attacks are aimed at specific individuals but have the potential to spread further if left unpatched. The fixes included in iOS 26.2 address vulnerabilities that Apple considers critical, making the update essential rather than optional.
What has raised concern is that these fixes are no longer being fully extended to older iOS versions. Users who remain on previous releases may not receive the same level of protection, increasing their risk of exposure.
Limited fixes for older iOS versions
Earlier, many expected iOS 26.2 to be a final, optional update, with security patches also reaching older versions such as iOS 18. That is no longer the case. Apple has restricted several critical fixes to specific iPhone models and software versions. As a result, users who avoid upgrading may find their devices missing important protections.
This decision effectively forces users on supported iPhones to move to iOS 26.2 if they want access to the latest security updates.
Additional protections introduced in iOS 26.2
Beyond security patches, iOS 26.2 introduces system-level protections aimed at reducing common attack vectors. These include improved safeguards in Safari to limit tracking techniques, stronger defenses against risky wired connections, and new anti-scam measures in calls and messages. Together, these changes focus on reducing everyday risks faced by iPhone users.
Why Apple says you should not delay
Apple’s message is direct: if your iPhone supports iOS 26.2, update now. With active threats confirmed and critical fixes tied to the latest version, running outdated software increases the risk of compromise. The update is positioned as a necessary step to keep iPhones secure in the current threat landscape.
