When you start Minecraft Java edition on mac with the option "Keep the Launcher open while games are running" deselected and click the Minecraft Launcher Application before java starts, the window for Minecraft Launcher opens but the macOS dock says Minecraft Launcher is not running. I am using the newest non-beta version of the launcher I could find on minecraft.net
