I know that there is mic problems with leopard with getting it to work and what not but i had to remove everything on the computer to start over and now i have dual boot windows xp and leopard but in xp my mic does not record audio and with your mouth really close to the screen it hardly picks up anything and what it does you can't understand is this a hardware issue if so im going to back up my hard drive and return it for a new one its still under warrenty
