On the latest macOS 27 beta, the fans stay on almost constantly even when the machine isn’t hot.
fans usually stayed off until ~60°C+ Now: fans kick in around 50°C and stay on at idle / light use
Anyone else seeing a lower fan curve and fans on at idle on 27?

I'm unable to join the waitlist or confirm whether I am on it. Photos AI and Describe a Shortcut work, along with the Cloud models in Shortcuts. Should I wait? How do I join the waitlist? What's going on?

In a previous post, I wrote about how macOS 27 allows agents from third-party apps to integrate with Siri AI, as an alternative to the ChatGPT extension.

Turns out, macOS 27 also allows third-party apps to replace Siri's model. In the video, Siri runs through OpenAI's GPT-5.6 Terra model.

With the new Inference Providing protocol, an app can replace Siri's agentic planner with a third-party model. GPT-5.6 receives Apple's native Siri planner prompt and 20 tool definitions. It can make tool calls that perform system actions, and receive tool call results with personal data. Finally, GPT-5.6 can give a response through Siri AI's UI and voice, including interactive elements.

Will this ship for apps in macOS 27? Only time will tell, but the building blocks are already there. Releasing an Inference Provider extension requires a private entitlement from Apple.

Internally, Apple uses an external inference provider that has supported OpenAI API-compatible models for a few beta cycles. In Beta 5, they added support for Gemini models in their internal extension. It does not ship with macOS 27.

edit: In the demo video, you're seeing a custom extension I built that relies on the internal InferenceProviding framework, and registers with a non-public ExtensionKit extension point: com.apple.modelmanager.inferenceprovider. Until Apple allows developers to build this type of extension, you'll need SIP off and AMFI disabled (amfi_get_out_of_my_way=0x1) to develop these tools.

Hi everyone, I'm very happy that Apple is updating its traffic lights for macOS (as my post history can attest 😉). They look a little squashed to me however and I thought of a little modification that might help making them look more round. Added highlights on top of the buttons. Let me know what you think. Will send feedback to Apple about this.

Golden Gate kinda feels like the second coming of Aqua and I'm loving it!

I know I’m nitpicking, but I genuinely don’t understand how we’re here again.

Last year, with 26 had the whole “different corner radii” saga. This year, Apple said they were committed to fixing those inconsistencies and paying more attention to detail with Liquid Glass.

But now we have Liquid Glass behaving differently within the same controls the volume slider is clear and glassy, while the brightness control looks much more matte and opaque, and even the corner radii don’t seem consistent.

EDIT: Here is the same display control with more liquid glass when opened from the control center, instead of the menu bar. same setting-same control-but different liquid glass.

Is it a bug, or is it a feature?

Or is Cupertino just performing human experimentation on us, in order to best find our pain threshold?

After updating to Beta 6, my menu Bar is gone and the wallpaper just turned to black.

Any suggestions of a fix?

What happened to my boy????

these buttons are not working, is anyone facing this issue. not sure if its in iOS 26.

Happy beta day!

As previously discussed, Apple is working on a dynamic solar wallpaper engine for macOS 27 that groups aerial Landscape wallpapers and automatically switches variants based on the sun's position during the day.

When properly configured, the four Tahoe and Golden Gate landscape wallpapers appear under one entry each in Settings, and a new Automatic display option appears.

Use these instructions to enable the Automatic Golden Gate and Tahoe landscape wallpapers.

For anyone that used the previous guide, the TahoeCombined feature flag override is no longer needed. You can safely remove it:

sudo defaults delete /Library/Preferences/FeatureFlags/Domain/Wallpaper TahoeCombined

There's no need to remove anything else. The linked guide will replace your previous wallpaper override file and combine all four Golden Gate wallpapers.

Two new wallpapers/screensavers!
