I don't have a solution for the windows/dock/menubar not behaving correctly (which is why I've only been using my MacBook 14inch screen after my monitor died a year ago). But my Lunar app (https://lunar.fyi/ https://lunar.fyi/) does have some solutions for the other problems: I have an iMac Pro. Even if I were willing to waste the built-in display, I cannot – Apple does not allow iMacs to disable their internal displays. Lunar can use a hidden macOS API to really disable the internal screen on Apple Silicon: https://lunar.fyi/pro#blackout https://lunar.fyi/pro#blackout It basically removes the screen from the Displays system settings and from the screen arrangement completely, and turns off its backlight. On Intel it can simulate that by mirroring the screen and turning it black which does the job for most people. It’s very distracting having a bright display right next to one on which you’re trying to play a game. Again, Blackout can help here with a handy action called "Make other screens black (keep this one visible)" which can be activated by Option-Shift-Click on the power button or with the finger-wrangling hotkey Ctrl-Opt-Cmd-Shift-6 (it can be re-assigned, I ran out of non-conflicting hotkeys) --- In the past, I spent a huge amount of time trying to fix the window problems using yabai rules (automating where windows should appear) and hotkeys for moving between displays. But it became a burden whenever I wanted to stray away from my pre-defined rules or when the cursor moved between displays erratically. Nowadays I have: • a single 14inch very bright and vivid display with a single Space/desktop • all my apps covering the whole screen • switching between apps with rcmd (https://lowtechguys.com/rcmd https://lowtechguys.com/rcmd) • ..and sometimes moving windows in a left/right pair with Swish (https://highlyopinionated.co/swish/ https://highlyopinionated.co/swish/)
