I bought a D-link dbt-120 "B4" and the mac doesnt recognize it. I called tech support and was told that this product is not compatible. I have the older Mac Mini 1.42ghz, 10.4.11 and want to use a wireless keyboard and mouse. Does ANYONE know for SURE which usb bluetooth adapters work with this computer?!! Can someone walk me through this? Also, heard something about a "802.11g to ethernet adapter"? Will that do it? And if so... how do I go about doing that? Thanks in advance people
