    So, I have a 13" rMBP and every time I open iMovie, I get a popup that says, "iMovie can generate new thumbnails of your video at a higher resolution. This may take several minutes."

    I'm guessing this is just optimizing thumbnails for the Retina display, but it asks me EVERY TIME! Anyone know if this is normal and if I can stop this popup from happening?:confused:
