Apple’s advice: Back up your device and apply updates via Settings → Software Update on iPhone/iPad or System Settings → Software Update on Mac. Avoid installing beta versions on primary devices.AppleVisTidBITS

The Road Ahead
With iOS 26 and macOS Tahoe 26 on the near horizon, the urgency to update dwindles—but security doesn’t wait. Apple will shortly shift focus entirely to feature‑rich updates for next‑generation OS releases.
Still, expect possible iOS 18.7 or macOS 15.7 patches in early autumn if critical issues arise before Tahoe ships. For now, these x.6 updates offer the last layer of protection in the current cycle.
Conclusion
iOS 18.6 macOS 15.6 updates represent Apple’s final maintenance of the current-generation operating systems. While devoid of new features, they deliver essential bug fixes—particularly for Photos and device restoration—and patch dozens of vulnerabilities across Apple’s ecosystem. With iOS 26 and macOS Tahoe imminent, now is the ideal time to ensure all devices are patched, secure, and ready for the next wave of innovation.
