You'll need the DVI/VGA adapter to plug it, in but the monitor should sync to a proper VGA signal.
Edit: I looked through the display adapters at Apple, however, and the only DVI/VGA adapters are for the computers...no guarantee it would work with monitor. I would suggest a nice inexpensive VGA flat panel for your Amiga if you get this for your Mac. I bought a 17" Apple display for my G5 tower. I think they're asking too much money for the display myself.
