Q: Great, but the article very carefully AVOIDS one key point: What do you do when the MUTE is checked but grayed OUT so that you can't uncheck it? This whole problem is ruining my MAC experience, since now mp4s won't play since there's an unexpected error
iTunes doesn't play the songs. And QuickTimePlayer won't play: The document “TestNewMac.mp4” could not be opened. An unknown error occurred (-101). Isn't this wonderful? I've seen 100s of articles and complaints about the same thing. How come Apple doesn't fix it? Now I want my money back. VERY Angry at Apple for these problems. Furthermore, the beachball of death spins for an unreasonable amount of time upon startup, and I have a solid state drive! Come on Apple. I bet my $4000 is working for you. How come your machine isn't working for me?
iMac, Mac OS X (10.7.4)
