Apple Seeds Fourth macOS Golden Gate 27.2 Beta to Developers

Just what I've always wanted new brightness and volume sliders!! Now THAT'S progress Apple devs!

Apple Developers: "We choose to change these sliders and do the other things, not because they are easy, but because they are hard."

Let's pray for the bugs

Being fixed or at least being worked on ( I hope they are listening )

Mission Control is a lot better in this beta. I've tried dragging around multiple windows across multiple desktops, and I'm not seeing invisible windows and animation glitches like I did before. However, I don't want to say it's back to normal just yet.

Also, some of the interface changes from the last beta (that were seemingly hinting at touch-screen optimisations) have been reversed:

The drag selection in Finder is squared off again, and holding app icons in the Dock no longer causes them to enlarge.

Let's spray for the bugs

Fixed 😜

Okay, the first to try the fourth beta please report if Mission Control is still broken or has been fixed

I'm not going to say Mission Control is fixed (it's not) but there's been alterations/progress in this new beta. The long delay when dragging a window to the top to create a new space is gone. Also when in a fullscreen app (lets say something like calendar) swiping up in Mission Control view and then selecting another running app in the dock (lets say safari) was previously just resulting in the OS returning to calendar. That's broken behaviour is now fixed for me. Also, I can't make it black screen when closing an app in fullscreen Split View.

However still janky/sluggish overall

build is 26B5112a
