I have tried to import the files from the hard drive, but the .mov files are grayed out. I connected the iPhone to the Mac and I can see/import the photos but the videos do not show up - just a blank screen. An earlier support solution to this problem linked to software to convert the file from .mov to mp4, but the software is not free - only a very limited trial is free. I'm having difficulty believing that the iPhone videos and iMovie are not compatible.
