To drop a stack on a mac requires pressing Cmd + Q. Unfortunately this by default is also a shortcut to quit Minecraft.
How I know Cmd + Q drops a stack:
Disabling the Cmd + Q = Quit shortcut by going into system preferences, keyboard, shortcuts, and binding "Quit Minecraft" to something else, like Cmd + Option + Q, enables me to drop a stack by pressing Cmd + Option + Q
My suggestion:
Rebind it to Ctrl + Q

@ezekielelin Are you sure? That issue report says "pressing cmd + Q does not quit the game", where as mine says it does quit the game

Ah, whoops. Give me a moment to fix that.
