I have to point to this thread in the Golden Gate subforum.


These terminal commands will disable the floating sidebar (first one) and set the window corner radius back to how it was in Sequoia (second one). To see the effect you have to close and relaunch your app after running the commands. (Log out and log back in to clean up "everything".)

defaults write -g NSSplitViewItemSidebarDefaultsToFloatingAppearance -bool false
defaults write -g NSConvolutionOverride1 -float 10

If you want to set things back to "default", use:

defaults delete -g NSSplitViewItemSidebarDefaultsToFloatingAppearance
defaults delete -g NSConvolutionOverride1

You can try different values for the window corner radius (second command). 26 is Tahoe's standard, 20 is Golden Gate's standard, 10 is for previous versions of macOS. You can set it smaller than 10, but some windows look a little weird in the corner if you do.

[Edit]
Disabling the floating sidebar seems to work in some apps (Finder, Calendar, Reminders, Notes) but not others (Weather, Maps, Find My).
