Why won't iTunes download HD movies? I'm running iTunes 11 on a retina MacBook Pro, and when I try to download HD movies, iTunes shows me a dialog alert saying "This  cannot be played in HD on this computer." The dialog goes on to imply that I have a choice to proceed or to but the standard def version, but I don't see a way to buy the HD version.



Why can't iTunes 11 play HD movies on a retina MacBook Pro? Where's the "I wanna download it anyway" button?
Open iTunes > go to Preferences > Downloads. Ensure that the checkbox which asks if you want HD footage to be preferred over SD is ticked. Also, check your storage and make sure you are using a screen resolution that isn't too far off from the default. If this does not work, turn off the computer, then press  shift + control + option, then press the power button (but don't hold). Then once you have done that, power on the computer. Some users who had this bug have reported that as a solution.
