There is something called DV MOTION for MAC. I'll find you a link for download.
Actually I tried this software on my Apple Laptop and it was almost like DV Rack. I accidently deleted it.

HD Monitor Pro allows users with a Panasonic HVX200 to view, focus, optimize, record and organize high definition and standard definition video directly to their Macintosh computer. Users see 1:1 pixel accuracy even if they are using a screen resolution less than the full 1080 HD screen resolution of 1920x1080. This allows pixel perfect focusing in real time even on a 12 inch laptop screen. HD Monitor Pro will allow users to zoom in up to 400% or to auto scale the video to fit any size window.
