Apple today provided developers with the third beta of an upcoming macOS Sequoia 15.3 update, with the third beta coming a week after Apple released the second beta.

macOS Sequoia Night FeatureRegistered developers can opt-in to the ‌macOS Sequoia‌ beta through the Software Update section of the System Settings app. An Apple ID associated with an Apple Develope r account is required to get the beta.

‌macOS Sequoia‌ 15.3 brings Genmoji to the Mac, a feature that was previously limited to the iPhone and iPad. With ‌Genmoji‌, Mac users can create custom characters with a text-based prompt, similar to how Image Playground works.

‌Genmoji‌ characters behave just like emoji on devices running iOS 18.1, iPadOS 18.1, ‌‌macOS Sequoia‌‌ 15.1 and later, but on earlier versions of iOS, macOS, iPadOS, and Android devices, ‌Genmoji‌ are sent as images. ‌Genmoji‌ can be added from the emoji interface, and image generation is done on-device.

All macs with an Apple silicon chip support ‌Genmoji‌ and other Apple Intelligence features.
