Apple has released the first developer betas for iOS 27, iPadOS 27 and macOS 27 "Golden Gate".
To install, you need a registered Apple developer account. Open the Apple Developer portal, locate the "Beta Software" section, and download the appropriate configuration profiles. After installing the profiles on your device, go to Settings → General → Software Update and tap "Download and Install". macOS users add the macOS 27 installer to the Software Update pane via the same profile.
The betas bring Siri’s new conversational AI, a Spatial Reframing camera mode and a refreshed lock‑screen design. Early access lets developers adapt their apps to the updated APIs before the public roll‑out in the fall.
Expect occasional crashes and missing features – beta software is still a work in progress, not a polished preview.
