macOS 27 Golden Gate – Review

Ars Technica reviews macOS 27 Golden Gate, highlighting an unavoidable Apple Intelligence upgrade, new AFM 3 Core models, and dropped Intel Mac support.

macOS 27 Golden Gate delivers the first significant Apple Intelligence upgrade two years after launch, and the toggle to disable the AI features or delete downloaded models is gone. Apple Intelligence runs on a new AFM 3 Core model built in collaboration with Google, while the more capable AFM 3 Core Advanced requires an M3 chip and at least 12GB of RAM. The release drops all Intel Mac support, requiring Apple Silicon, with Sequoia security updates expected to end in fall 2027 and Tahoe's in 2028.

Apple iCloud Private Relay Can Expose Real IPs Through WebKit Proxy Bypasses

Researchers found WebKit features bypass proxies and iCloud Private Relay, leaking users' real IP addresses; Apple patched in iOS 26.6.1 and macOS 26.6.2.

Researchers Talal Haj Bakry and Tommy Mysk found that three WebKit features — DNS prefetching, WebAuthn Related Origin Requests, and WebTransport — bypass configured proxies and send traffic directly from the device. This leaks the user's real IP address in Safari and all WebKit-based iOS browsers and undermines iCloud Private Relay's dual-hop privacy design. Any website can trigger the leak via WebAuthn without user interaction or passkey use; a proof-of-concept site, leaks.psylo.app, demonstrates the issue. Apple investigated and patched the leaks in iOS 26.6.1 and macOS 26.6.2.

27.5KB language-agnostic WebGPU syntax highlighter

A developer released gpu-lexer, a 27.5KB language-agnostic syntax highlighter that uses a tiny WebGPU model to label code tokens in the browser.

gpu-lexer splits source into words, whitespace, and symbols, then a small WebGPU model uses local and whole-file context to assign nine token classes, working on languages never seen in training. On held-out files, 12.57% of token labels differ from Shiki, though this measures agreement with Shiki rather than objective correctness. In benchmarks against Shiki 4.4.3, Prism.js, Highlight.js, Sugar High, and Starry Night, it highlighted 10 concatenated copies of three.min.js (5.56M characters) about 10x faster on an Apple M4 Pro in Chrome 152. The author frames it as an experiment, not a grammar-equivalent highlighter.
