Apple today released iOS 18.4.1 and iPadOS 18.4.1, minor but important updates to the iOS 18 and iPadOS 18 operating systems for the iPhone and iPad, respectively.
The new software can be downloaded over-the-air on compatible iPhones and iPads, by going to “Settings” -> “General” -> “Software Update.”
