Introduction
Apple has a long-standing policy: you must upgrade to the latest iOS version to receive security patches. But in April 2026, the company broke its own rule. The release of iOS 18.7.7 for devices that can run iOS 26 marks a rare “backport” – delivering critical security fixes to users who chose to stay on the older operating system. This move, part of the broader apple iphone security changes in response to the DarkSword exploit, protects an estimated 16% to 20% of newer iPhones still running iOS 18.

What Is a Backported Security Patch?
A backported patch means taking a security fix originally developed for the latest operating system (iOS 26) and making it work on an older version (iOS 18). Apple rarely does this. Typically, the company urges users to upgrade to the newest OS to stay protected. However, the severity of the DarkSword exploit forced a change in strategy.
Why Apple Changed Its Policy
Several factors drove Apple’s unusual decision:
- Slow iOS 26 adoption: An estimated 16% to 20% of newer iPhones (models 11 through 16) are still running iOS 18. That is roughly 270 million vulnerable devices.
- Liquid Glass backlash: Many users refused to upgrade to iOS 26 because they disliked the controversial Liquid Glass interface, which received mixed reviews for its translucent design.
- DarkSword’s severity: The exploit kit can remotely install malware simply by visiting a compromised website. Apple warned: “If you’re using an older version of iOS and were to click a malicious link or visit a compromised website, the data on your iPhone might be at risk of being stolen”.
- Criticism of Apple’s patch policy: Security researchers and users criticized Apple for leaving iOS 18 users exposed while pushing them to upgrade. As 9to5Mac reported, “Criticism of Apple’s lack of backported patches for iOS 18 had grown over the past two weeks, as DarkSword proliferated among hacker groups”.
The Two-Phase Rollout of iOS 18.7.7
Apple released iOS 18.7.7 in two phases:
| Phase | Date | Devices Covered |
|---|---|---|
| Phase 1 | March 24, 2026 | iPhone XS, XS Max, XR (models that cannot run iOS 26) |
| Phase 2 | April 1, 2026 | All iPhone 11–16 models, iPhone SE (2nd/3rd gen), iPhone 16e, and numerous iPads |
Apple confirmed the expansion: “We enabled the availability of iOS 18.7.7 for more devices on April 1, 2026, so users with Automatic Updates turned on can automatically receive important security protections from web attacks called DarkSword”.
Which Devices Receive the iOS 18.7.7 Backport?
The update is available for the following devices:
- iPhone XR, XS, XS Max
- iPhone 11, 12, 13, 14, 15, 16 (all models)
- iPhone SE (2nd and 3rd generation)
- iPhone 16e
- iPad mini (5th generation – A17 Pro)
- iPad (7th generation – A16)
- iPad Air (3rd – 5th generation)
- iPad Air 11-inch and 13-inch (M2 – M3)
- iPad Pro 11-inch (1st generation – M4)
- iPad Pro 12.9-inch (3rd – 6th generation)
- iPad Pro 13-inch (M4)
How to Install iOS 18.7.7
- Open Settings > General > Software Update.
- On older iPhones capped at iOS 18, you will see iOS 18.7.7. Tap Update Now.
- On newer models still running iOS 18, Apple will offer both iOS 18.7.7 and iOS 26. Choose the iOS 18 update to stay on the familiar interface while receiving critical security fixes.
- Enable Automatic Updates to receive future backported patches automatically.
What Does This Mean for Apple’s Future Update Policy?
This apple iphone security change signals a potential shift in Apple’s long‑standing approach. As Help Net Security noted, “Allowing iOS 18 users to receive patches without upgrading to iOS 26, however, signals a shift in its long‑standing security approach following the discovery of the DarkSword exploit kit”.
The Hacker News added: “While Apple is known to backport fixes for older devices depending on the criticality of the vulnerabilities, the move to allow iOS 18 users to patch their devices without having to update to the latest operating system version marks an unusual departure for the tech giant”.
Nevertheless, Apple still encourages users to upgrade. The company said: “We encourage all users with supported devices to update to iOS 26 to receive our most advanced protections”.
Comparison Table – iOS 18.7.7 vs. Standard Update Policy
| Aspect | Standard Apple Policy | iOS 18.7.7 Backport |
|---|---|---|
| Upgrade required | Yes (must move to iOS 26) | No (stay on iOS 18) |
| Devices covered | Only devices that cannot run iOS 26 | All devices still on iOS 18 |
| Reason for update | Routine security fixes | Critical zero‑day exploit (DarkSword) |
| User choice | Limited to upgrade or remain vulnerable | Can choose to stay on iOS 18 and remain secure |
| Future precedent | Rare; not guaranteed for all vulnerabilities | May signal more backports for severe threats |
Real‑World Applications of the iOS 18.7.7 Backport
- For everyday users: You can now keep the iOS 18 interface you prefer while staying protected from DarkSword.
- For businesses: IT teams can defer the iOS 26 upgrade without compromising security.
- For Apple: The move acknowledges that forcing users to upgrade is no longer always feasible.
- For security researchers: Backporting may become more common for critical vulnerabilities.
FAQ Section
Q1: What does “backport” mean in the context of iOS 18.7.7?
A: Backporting means taking a security fix originally developed for iOS 26 and adapting it to work on iOS 18. Apple rarely does this, but the severity of the DarkSword exploit forced the change.
Q2: Why did Apple release iOS 18.7.7 instead of just pushing users to iOS 26?
A: Approximately 16–20% of newer iPhones still run iOS 18. Many users refused to upgrade due to design changes like the Liquid Glass interface. Leaving them vulnerable would have created a massive attack surface.
Q3: Do I need to upgrade to iOS 26 after installing iOS 18.7.7?
A: No. iOS 18.7.7 provides the same DarkSword protections as iOS 26. However, Apple recommends upgrading to iOS 26 for “the most advanced protections.”
Q4: Will Apple backport future security patches to older iOS versions?
A: Possibly, but only for critical vulnerabilities. This move was unusual, and Apple has not committed to a permanent policy change.
Conclusion
The iOS 18.7.7 backport represents a significant apple iphone security change. For the first time, Apple delivered critical security patches to millions of users who chose to stay on an older operating system. This decision acknowledges that forcing upgrades is not always practical and that user choice matters. However, Apple still encourages everyone to move to iOS 26 for the best protection.
