Continuing Apple's weekly test releases ahead of the official launch of macOS 27 Golden Gate, the company is now rolling out beta 8 for developers. While macOS 27 Golden Gate beta 7 didn't include any notable user-facing changes, beta 6 introduced redesigned traffic light window controls with a more Liquid Glass-like appearance. At this stage of the beta cycle, Apple appears to be increasingly focused on bug fixes, performance improvements, and other under-the-hood changes ahead of macOS 27's public release.

macOS 27 Golden Gate introduces the new Siri app alongside Apple's revamped Siri AI, as well as an AI-powered Shortcuts app that can create shortcuts from natural-language prompts. Safari also gains a prompt-based extension builder. The update additionally includes new Golden Gate-themed wallpapers and screensavers, while restoring fixed-radius corners for windows and apps after macOS 26 introduced dynamically changing corner radii.

Installing the macOS 27 Golden Gate beta: Back up your Mac, open System Settings, go to General ⌸ Software Update, click the 'i' icon next to Beta Updates, select the macOS Developer Golden Gate Beta from the dropdown menu, and hit 'Done'.
