On Monday, Apple stopped signing the code for iOS 14.6 following the release of iOS 14.7 last week and iOS 14.7.1 today, meaning that users are now unable to downgrade to the previous version of the operating system.
Earlier today, iOS 14.7.1 was released to fix an issue that was preventing Apple Watch from unlocking iPhones with Touch ID. The update also closed a potentially serious security hole that was exploited in the wild.
Users who upgraded to iOS 14.7 or iOS 14.7.1 can no longer download or install the now outdated iOS 14.6 operating system.
Apple routinely stops signing legacy code after the release of a new build of iOS, in part to protect customers from nefarious actors trying to exploit newly discovered vulnerabilities. In addition to security, preventing users from downloading older codes allows Apple to keep more iOS devices with the latest and feature-rich software.
The company has yet to release a beta version of iOS 14.8, but the company is working on the next milestone release of iOS 15 that will debut this fall. That update will bring a host of new system tools and enhancements to proprietary apps like FaceTime, Maps, Messages, Safari, and more.
