Apple Seeds Second Beta of macOS Monterey 12.4 to Developers

Apple today seeded the second beta of an upcoming macOS Monterey 12.4 update to developers for testing purposes, with the new update coming two weeks after the release of the first macOS Monterey 12.4 beta.

macOS Monterey 2
Registered developers can download the beta through the Apple Developer Center and after the appropriate profile is installed, betas will be available through the Software Update mechanism in System Preferences.

According to Apple's release notes, Universal Control in the new iPadOS 15.5 and macOS Monterey 12.4 updates is not compatible with machines running macOS 12.3 or iPadOS 15.4, so Apple suggests that as a workaround, users should update their ‌Universal Control‌ devices to the new betas.

We don't yet know if there are any other features in macOS Monterey 12.4, and nothing new was discovered in the first beta.

Another release candidate version of macOS Big Sur 11.6.6 has also been seeded.

That ain't coming..

I've sorta been convinced from other comments, more or less "theres no way apple pushed out this monitor without knowing the quality of webcam recording and that this firmware bug, just snuck up on them."
It’s the identical camera and CPU from the iPhone 11.
It’s been confirmed by several people who *don’t* work for Apple that it is clearly a software issue.

Given that there’s only been one update, and it was the update that was already installed on all of the review units, let’s just give it time.

Here's hoping this version fully realizes what the U in USB stands for. I miss "just works."

And while they are at it, how about supporting the full speeds of the jacks too? ('https://eclecticlight.co/2022/04/18/m1-thunderbolt-ports-dont-fully-support-usb-3-1-gen-2/')

I'm hoping for a Snow Monterey year announcement at WWDC... maybe even 2 years of Snow if they need it.
