When I'm watching a movie and I press the "play" button, iTunes 10 launches. How can I keep this from happening?

Just found this on Lifehacker. I think it's exactly what you're looking for. The post talks about a patch called MMFix, which changes the media control daemon to stop exactly this from happening. Apparently, it comes with a one-click installer.

And, if some reason you would like to remove the patch, just run the one-click installer again and the original rcd daemon will be restored.

(Works on OS X 10.7 Lion, too!)

  • Sounds great, i will try it :-)

MMFix hasn't been updated for Mountain Lion yet, but I did find this solution to work, run

launchctl unload -w /System/Library/LaunchAgents/com.apple.rcd.plist

in the Terminal.

    Keep in mind though that this disables the functionality of the media keys in iTunes itself as well. Jan 19, 2013 at 13:09

    @user2113 Yes, probably. Although I don't know for sure. Feb 26, 2014 at 18:04

iTunesPatch did the trick for me on OS X Yosemite.

Description from website:

The application will patch the Remote Control Daemon to prevent it from starting iTunes whenever you press the play button on the keyboard or an external remote control. This will only prevent iTunes from starting, all other functions (like play/pause while iTunes is running) will continue to work as before. The original file is backed up in case you would like to restore the original functionality.
