I have a Sagem F@st 800 modem (came free from our ISP, Tiscali) which simply refuses to work on my (just arrived today) Macbook. The installation CD that actually came with the modem does include installation files for OSX, and the modem does appear to install without error. However, after the obligitary restart when the installation finishes, there is no message saying a modem has been detected (like the instructions say there should be) and nothing appears in Networks. I am absolutely baffled as to why it won't work. It works fine on my PC, so its not the modem. Nor is it the USB port, as the modem is detected during install. Its after the install that the Macbooks acts as if the modem is not connected! I'd greatly appreciate any help guys! Thanks!
