[filiphdan]

Hi,

I have been having some problems whit my access virus ti2 and i want to try the new update to see if it solves some of the weird stuff that happens whit it, well ive read that you need to unistal all the previous drivers, my question is how do i do this in the mac? ( i´m new to mac ) if i was in windows i simply would go to the control panel...
If anyone could help me here
