Apple's latest software rollout hit a snag last week when the first iOS 18.4 beta was pulled from certain devices after causing critical problems.
While the beta was initially released for developers to test, issues with the update led to its removal for several iPhone and iPad models.
Specifically, users with iPhone 12 mini, iPhone 12, iPhone 12 Pro, and iPhone 12 Pro Max were no longer able to install the update, alongside some older iPad Air and entry-level iPad models.The problem stemmed from the update triggering a "boot loop" on some of the affected iPhone 12 models, rendering them unusable.
As a result, Apple advises users to back up their devices before installing beta software, as early releases often carry the risk of critical bugs.
In addition to the boot loop, there may have been other issues affecting cellular versions of the iPad Air, although the exact nature of these problems remains unclear, according to a report by MacRumors.
