macOS 27: new Siri takes on AI productivity apps

Siri can also now help you with reviewing documents or performing writing tasks. Since the desktop is one of the better surfaces for writing long text, I found it to be more useful here than on the iPhone. You can do things like select a block of text and ask Siri to proofread it, improve it, or rewrite it. You can also ask Siri to draft something for you within any text box.

Safari, meanwhile, has added AI-powered page tracking, which is useful for keeping an eye on things like price drops, privacy policy changes, or new blog posts on pages when there is no RSS support. Plus, Safari can automatically organize tabs based on topics, which is handy.

One small but neat new feature is that when you download a file or rename it, the system suggests a name based on context in the Finder or when you’re saving the document.

Apart from Siri, macOS 27 Golden Gate brings design changes with new Liquid Glass icons, an adjustable slider for the Liquid Glass design, and a better way to “diffuse” content when you move windows around.

The company said that app windows have a more consistent corner radius. Sidebars now stretch edge to edge and have new colorful icons. The new operating system update also better highlights active windows.

The OS update additionally adds features like enhanced child safety controls, shared cross-platform photo albums, and an updated eraser, better search in email, app resizing for iPhone mirroring, and quick suggestions for adding events to the calendar.

Starting today, macOS 27 Golden Gate is available for MacBook Air and MacBook Pro 2020 version with Apple Silicon or later, iMac with Apple Silicon (2021 or later), Mac Mini (2020 or later), Mac Studio (2022 or later), Mac Pro (2023 or later), and MacBook Neo. Go to System Settings > General > Software Update to get the latest version.
