Camera playback on computer

I'm trying to playback some video recorded from today, on our MacBook pro.  I can get a live feed visual from the camera from my computer.  I see all the list options that were recorded on the device today.  But I cannot get them to play for me on the laptop.  I can get them to play on my iPhone, but it's too small for us to see and we are trying on a bigger screen, hence the need to get it to playback on the laptop.  When we hover over it shows the hand/click symbol.  But when I click or double click, it doesn't play anything back.  Any suggestion welcome.  Hopefully soon, before the videos disappear.
