Apple releases new beta versions of macOS Sequoia 15.1 and watchOS 11.1

macOS Sequoia 15.1 beta features Apple’s first Apple Intelligence features for Mac. Developers will now have access to features like Writing Tools, enhanced Siri capabilities, and Smart Replies in Mail and Messages. The inbox in these apps can also be filtered with the help of artificial intelligence.

However, other features such as Image Playground, which allows on-device image creation, Genmoji and ChatGPT-powered Siri are not yet available in the beta. Apple Intelligence features will be available on Mac devices with Apple silicon chips.

As for watchOS 11.1, artificial intelligence features have not yet been clearly shared. It is possible to say that watchOS focuses on basic features and metrics instead of Apple Intelligence capabilities in macOS and iOS.

For testing purposes, developers can download and install both beta versions via the Apple Watch app on iPhone. Developers can test the new update by going to System Preferences > Software Update on Mac/Apple Watch devices paired with an Apple ID.
