QuickTime autoplay on open does not work

Question

verityj opened this issue a year ago · comments

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?
