how can I get my airport software to recognize my airport hardware? the mac store genius bar employee said, that limewire or someone left something on my hard drive that is blocking my computer from recognizing my airport hardware. I have a mac ibook g4 with a airport built in. The airport was found by the employee at the store so it is working. He suggested I erase my hardrive and start fresh is there anyway around this? I deleted my itunes hoping that would help it did not. Is this a common problem and how can I fix it? I have limited computer knowledge and thank you for your help mark.
