iOS 15.4, the latest version of Apple’s iPhone operating system, has been released and should soon be available for download ahead of the Friday release of Apple’s new third-generation iPhone SE and green iPhone 13. The update includes big new features like the ability to use Face ID while wearing a mask, as well as smaller additions like a handful of new emoji. The new version of iOS launches alongside iPadOS 15.4 and macOS 12.3, which add support for Apple’s new Universal Control feature.
Universal Control lets you use a Mac’s keyboard and mouse to control an iPad completely wirelessly, including the ability to drag and drop files from the tablet to a computer. Universal Control requires your Mac to be running macOS Monterey 12.3, which was also released on Monday, and the iPad to be running iPadOS 15.4.
We already have a pretty good idea of how Apple’s new mask-compatible Face ID implementation should work after trying it out in beta. You can read our full thoughts here. In short, it does a decent job of recognizing faces even when the nose and mouth are covered by a mask, but can still get tripped up by goggles, sunglasses, and floppy hats. Apple warns that enabling the new feature could make Face ID less accurate overall.
Other features include new anti-harassment features for Apple’s AirTag trackers as well as a new, more neutral Siri voice. There’s also support for a new Tap to Pay feature that lets iPhones accept contactless payments, though third-party providers like Stripe will have to add support to make it useful.
iOS 15.4 will be available for all iOS 15 compatible devices, meaning everything from the iPhone 6S is covered. iPadOS 15.4, meanwhile, is available for all iPad Pro models, the second-generation iPad Air and above, the fourth-generation iPad mini and above, and everything from the fifth-generation iPad onwards. base and later.
Finally, macOS Monterey 12.3 is supported on the following: iMac (Late 2015 and newer), iMac Pro (2017 and newer), Mac Pro (Late 2013 and newer), Mac Mini (Late 2014 and newer) ), MacBook Pro (early 2015 and newer), MacBook Air (early 2015 and newer), MacBook (early 2016 and newer).
