Late last week, Apple stopped signing iOS 15.4 following the release of iOS 15.4.1, making it impossible for users to downgrade their iPhones’ software. But the change also inadvertently stopped people from updating their new Studio Displays’ firmware, based on iOS.
Complaints ensued on Sunday. And before the end of the day, Cupertino re-signed iOS 15.4, making it valid and verifiable to servers again.
Did Apple release the $1,599 Studio Display with so much fanfare only to forget about it when it launched iOS 15.4.1?
