Big find for me on Beta 7 - Cisco Secure Client AnyConnect VPN.... if you disable the Socket Filter/Network extension (but leave the main one enabled), it will let you connect to your VPN!
 
In macOS 27 Beta 7, the option to use the Apple Foundation Model on Private Cloud Compute has been removed from the Apple Foundation Models CLI. Now, the fm CLI can only use the on-device Apple Foundation Model.

ffs. Thanks devs who abused this.
 
In Beta 7 across OS releases, Apple added new infrastructure to support dynamic wait time messages when a user joins the Siri AI waitlist.

 
They need to make them flat when inactive like literally every other button
In screenshots, the inactive buttons look oval, but they look particularly oval in actual use on my MBP. It reminds me of how icons looked tilted in the ‘26 operating systems because of the slanted angle of the highlights. I’m not sure if the solution is to flatten the inactive traffic light buttons, but I’m not opposed to that idea.

While I’m on my soap box, title bars and other elements of the system seem even more transparent in beta 7, which is extremely disappointing.

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. The post shows Claude acting as a Siri Extension. Turns out there are more hints across the OS about this feature.
