I am new to MAC's and need some help form some pro's. I just upgraded my iMac DV 400 to OS 9.1 (had 8.6) and my modem is not found. It worked fine before I upgraded so I dont think its a hardware problem. As far as updates go, I downloaded Apples Modem Update 2.0 but it wont install, because it cant find the modem. I have tried to change the modem properties (Connect via) to "Internal Modem", but I can not change it! Its set to "No serial port available". Please help!
