Apple encountered issues with the latest beta software updates for iOS 18.4 and watchOS 11.4, prompting the company to pull them from specific iPhone, iPad, and Apple Watch models. The problematic updates caused boot looping on certain devices, rendering them unusable. This is not the first time such issues have occurred with beta software releases, highlighting the risks associated with testing unreleased software on older models. Apple is expected to re-release the updates once the issues are resolved.
