Apple released its latest 26.5 software updates today, but the company also pushed new patches for users sticking with older operating systems. iOS 18.7.9, iOS 16.7.16, and iOS 15.8.8 joined the update lineup, alongside corresponding iPadOS versions and two macOS updates.

The older iPadOS updates include versions 18.7.9, 17.7.11, 16.7.16, and 15.8.8. Mac users can grab macOS Sequoia 15.7.7 and macOS Sonoma 14.8.7. These releases focus on security improvements rather than new features.

Apple's published security notes for iOS and iPadOS 15.8.8 reveal the update carries the same notification security fix that shipped in iOS and iPadOS 26.4.2 last month. The company continues supporting older OS versions with critical patches even as it rolls out major updates.

Users running these older versions should update to get the latest security enhancements. Apple maintains support for several previous iOS and macOS versions with security patches, ensuring devices remain protected years after purchase.
