I've got windows 10 on my PC. I have a neighbor that has a MAC using it for their security system. They gave me a USB drive to show the people trying to break in to their front door so I could see what happened. I cannot convert the seven MAC .mp4 files to view on my PC. I tried converting the files to several other formats, but none will run on my PC. I found a free program online called, Media Plater Classic Home Cinema, and I can play the MAC files on my PC. But only play, which is great to see the bad guys. in the seven MAC .mp4 clips. How can I open those video files so I can copy and send the videos to the cops from my PC.
