Apple regularly releases software updates for the company’s many platforms, mobile and desktop alike. Interestingly, while most Apple’s software updates target either newer devices or upgrading the user experience of the company’s latest firmware iteration, a few heads turned when Apple released iOS 12.5.1 earlier this month to address a COVID-19 exposure notification bug that purportedly affected older iPhones.
Given that a software update was released, despite being for an older iteration of iOS, it should come as no surprise to anyone that Apple would soon close the signing window for what was previously the latest version of iOS 12. This happened Tuesday evening after Apple officially made the move to stop signing iOS 12.5, the predecessor of the newer iOS 12.5.1 update.
