Q: QuickTime 10.4 (Sierra) won't autoplay movies.

For the life of me I cannot remember if this has started with the installation of Sierra, or right after, or right before. I don't think it's Sierra at all, I think at some point in the past few days I've done something somewhere that's changed/affected QuickTime's behaviour.

Now when I open whichever video file in QuickTime, it doesn't automatically play, I need to hit the play button manually. Movies have always autoplayed ever since I can remember, and I definitely don't like this issue. I've already tried the following command in Terminal...several times...didn't work.

defaults write com.apple.QuickTimePlayerX MGPlayMovieOnOpen 1

MacBook Pro, macOS Sierra (10.12), 17'' Late 2011

I'm pretty sure it is a Sierra issue... I'm seeing the same thing after upgrading, and searching Google comes up with someone else saying the same thing about the beta back in July

You think? All I've found on Google and also Youtube (lots of videos) is pretty old stuff, before Sierra. So I guess it's not a new issue at all, people have had it before. Not me though, so in my case as said I don't know if I did something myself or if it's Sierra. Anyhow, a solution would be very nice since that Terminal command does not work for me. And that seems to be the only solution available, or at least that I've found myself.

There is no solution.

It sounds kinda weird to me...that there's no solution to such a simple issue.
That was solvable in the past, because that Terminal line I posted did work in older OS X's.
I hope they'll fix this, or someone comes up with a new Terminal command!
It's nonsense, having to manually hit the play button when opening a movie in QuickTime in 2016!
