New Delhi: The latest iOS 15.4 update that has been announced adds the ability to unlock devices while having a face mask on. The latest update from the iPhone maker lets users unlock their devices via Face ID even while wearing a mask. It will function as the normal ‌Face ID‌, but scan the areas around the user's eyes for authentication. Apple is also rolling out iPadOS 15.4 that adds features such as Universal Control, thus, letting multiple Macs and iPads be controlled with the same mouse or trackpad and keyboard, the media has reported.


Universal Control feature requires user's Mac to be running macOS Monterey 12.3, which was also released on Monday and iPad to be running iPadOS 15.4.
