ExpertFlyer is a website, KVS is a Windows program, so you could only use ExpertFlyer on a Mac without somehow running a copy of Windows. To answer your second question, yes, and ExpertFlyer has the added unique benefit of alerting you when award/upgrade inventory opens up that currently isn't available, as well as specific occupied seats on a flight.
