Apple Seeds Second macOS Sierra 10.12.1 Beta to Developers and Public Beta Testers

Apple today seeded the second beta of an upcoming macOS Sierra update to developers and public beta testers for testing purposes, nearly a week after seeding the first beta and a week after releasing the new operating system to the public.

macOS Sierra 10.12.1 beta 2, build 16B2333a, can be downloaded from the Apple Developer Center (developers only), Apple's beta testing website (beta testers only) and through the Software update mechanism in the Mac App Store for those who previously installed the first 10.12.1 beta.

macOS Sierra 10.12.1 appears to focus on bug fixes and under-the-hood performance improvements to address issues that have been found since the operating system's release. Few outward-facing changes were discovered in the first beta, but it does include Photos support for the new iPhone 7 Plus Portrait feature introduced with the iOS 10.1 beta.

Any new features that are discovered in the second 10.12.1 beta will be listed below.

macOS Sierra is a significant update that brings features like Siri support, a new storage optimization option, cross device copy paste, auto unlocking with the Apple Watch, and more.

10.12.1 beta 1 brought newer and better drivers for Polaris GPUs. It added a new kext file AMDRadeonX4100.kext which solely contains PCI IDs for Polaris 11 GPUs.

Why can't I type into Siri? So it's maybe merged with Spotlight? Does Apple expect me talk to my computer in a quiet office with a dozen other people?

Possibly related to the new Macs?
Absolutely. A handful of people (myself included) have tried RX 460/470/480 GPUs in the tower Mac Pro with success. Fiji GPUs benefit from these new drivers as well.

I don't think they expect you to do anything. If you can't use it in your office, then don't. It's a feature that requires your voice. Getting upset at a feature for things it wasn't designed to do just seems silly.
