I have powerbook g4 1ghz with 1.5 ghz ram and the serato video worked but keep in mind my system is way way below specs. the video was clear but very choppy however I do see potential and will be upgrading to a macbook 2.0 ghz very shortly. Good job Serato. Oh by the way I also have VDJ and PCDJ, and serato is way better than all of them!
