defaults write com.apple.QuickTimePlayerX MGPlayMovieOnOpen -bool true
It gets written into the .plist just fine but when I open an .mp4 in QuickTime 10.5 it does not autoplay.
(I also tried defaults write com.apple.QuickTimePlayerX MGPlayMovieOnOpen 1 - same outcome, no autoplay)
Did the command change?
