I’m baffled by how Balkanized and weird the macOS interface has become of late. The control center menubar replacements from Monterey are completely inoperable with keyboard controls, and it looks like that backward slide into inaccessibility continues in Ventura. What happened? Apple still has an HIG page - are teams just totally siloed and allowed to deviate from those existing standards whenever?
