I finally figured out how to get internet on OSX. Go to System Preference > Network. Configure using Built-in Ethernet, use PPPoE, enter username and password. Go to Internet Connect under Applications X and login.
Took me a wee bit of trouble to download firefox 1.0 (only had 0.9.3 previously), but this is the first post on OSX, via firefox. YAY! At last.
Don’t quite like the faded colours and large menu fonts on OSX. And Verdana looks different, more square, more squished.
But it’s worth switching, though it’ll take a fair bit of getting used to.
