Hi Guys. I'm new here And I'm new in OSX world... I'v installed OSX 10.5.4 on my AMD phenom x3. Strange thing is when I go to Mac Properties I can see total number of Cores = 1.That is one thing I don't understand... Other thing that is confusing me is Wireless card. I have AirLive WT2000 PCI card and I was sending e-mail to tech support of AirLive asking for drivers for 10.5 and they have sent me. Those are drivers for Railing RT61. I install them but there is no AirPort showing up after installation. Do you have idea what could be a problem. Thanks!
