One of the easiest ways to get the footage into a Mac is the following:
1) Install Final Cut X
2) Open a new event and name it
3) Open a new project and name it the same
4) Put the SD card in the side of the Mac
5) If it hasnt asked you if you want to import something then hit apple+i
6) Choose the files you want to import and click 'import'
7) Depending on how much footage you have this may take quite a while to process
it will convert the files into ProRes422
8) To find the new processed ProRes422 files:
a) get a new finder window
b) under movies go to final cut events
c) one of the files has 'high quality media' these are your ProRes422 files
copy them wherever you want and use them.
Easier still use Final Cut X and edit it in there, it has finally become a very good program.
If you are using CS5 or CS6 (both better than Final Cut 7) the new converted files will work great.
