Here’s What’s New in the Second Public Betas of IOS 27 and MacOS 27.
Apple has released the second public betas of iOS 27 and macOS 27—just a week after launching the first public beta—so anyone who signed up for the beta program can now test the latest public version of the software on their compatible iPhone and Mac.
The most significant new features in iOS 27 and macOS 27 revolve around Siri AI , Apple Intelligence tools , Liquid Glass tweaks , and performance improvements; so if you don’t want to wait for the full release in the fall to try them out, you can install the public betas as they become available.
iOS 27 and macOS 27 Updates (Public Beta 2)
Last week, Apple released iOS 27 and macOS 4 developer beta, which 9to5Mac notes are the same build as public beta 2. While the macOS 27 update appears to primarily contain bug fixes and minor performance and stability improvements, the latest developer beta of iOS 27 also brings more significant changes .
For example, Siri has received several additional voice options, as well as a new Siri AI splash screen explaining its features when you first launch it. Control Center now features an Adaptive Mode slider for AirPods Pro, and the TV app automatically downloads upcoming episodes of the shows you’re watching and deletes downloaded files to save space. You can also adjust the text preview size in chat lists, and the “Enlarge photos to fill screen” feature allows images to automatically fill your device’s screen.
How to test the iOS 27 and macOS 27 public betas
Anyone with a compatible device can try Apple’s public betas—you just need to register your Apple account for the Apple Beta Program . We’ve previously covered this process for iOS 27 and macOS 27 , including a list of devices eligible for the update and the potential risks associated with installing a public beta. While public betas are generally safer than developer betas, they’re not perfect, and there’s always a chance of bugs. At the very least, you should make sure you have a backup of your data just in case.
