If your device can’t run iOS 17.0.1, Apple is also releasing iOS 16.7, macOS 12.7, and macOS 13.6 to iPhone and Mac users to fix a few vulnerabilities exploited by attackers.

On Apple’s security releases page, the company explains some of the fixes these updates bring, as they impacted the Kernel, Security, and WebKit sections of iPhone and Mac devices.

So, if you can’t get iOS 17 or macOS Sonoma, make sure to update your old iPhone and Mac to the latest version to protect your data and devices, such as iOS 16.7.
