Try Share/Computer/MOV (Quicktime).
This will output a DV-MOV, which will be a standard def editable video file. There are different outputs for creating a hi-def file. (MOVs are not your only options for Mac-compatible files.)
But if you just want your friend to be able view the file, use the Share/Mobile Phones and Devices/iPad. This will create a nice, clean MP4 that should play and look great on his Mac.
