None of those work for Macs to use for voice or cams, I just bought a new Macbook with a built in cam and mic, but i cant even use it. So far the only way i can use it with other people is if i pay for a Mac Ichat account, thats BS! With yahoo i can get the cam to work, but no voice, with msn i get nothing, i even went thro a jabber account thro ichat, to see if that works, nope! Anyone had better luck than me?
