Thank you. Thank you. Thank you. You and ONLY you mentioned “Nuendo restart required”. I tried going back and forth between dark and light while in Nuendo. Closing nuendo, and then going to Light mode, allowed me to at least be able to read the menus and have a mouse cursor. Simple things but necessary. However, I still maintain emphatically that forcing Mac users to use Light Mode (hate it, all my devices use Dark mode) is a BUG. Although it seems to be a bug Steinberg has no interest in addressing. That makes me sad.
