I saw beta screenshots of what used to be the toolbar (e.g. in Finder) and immediately disabled auto-update on my Mac. Seeing how many bugs have also been introduced (not just visual glitches) pretty much reaffirmed me in my decision.

However the downside is I can't try some new app releases like Daft Music[1] because it has become to burdensome to maintain two different designs. Especially in SwiftUI.
