I need a program so my videos will appear on my computer, so far when I try to open my USB folder nothing appears... like my camcorder is empty :Z I don't know what to do put I think I need a program for it

I have a Panasonic camcorder (nv-gs15eb) and I have some instructions about programs and such but only for Windows and I have a Mac Book, so please tell me how I can but my videos on my computer !

The reason why this is ergent is because I'm giving a presentation tomorrow and I really need my videos ... thanks for reading
And yeah it records onto a MiniDV tape
