I'm lost, how do I do this? I have 3 mobile internet modem plugged into my pc. I have a wireless router that both my mac and my laptop are connected to. I want to be able to use the pc's net access on my mac. I have been searching for guides but the steps show options that aren't available on my os for some reason (10.5.6) such enabling windows sharing within the sharing screen on mac, that service isn't listed. Thanks in advance.
