I've been having trouble connecting my 12" powerbook to other computer. I am currently running 10.2.3. I'm trying to transfer some files from my powerbook to my imac. when i search for my computer, it cannot find it or if it does it gives me a error message. I took my laptop over a fellow ibook user, and he can find my laptop when he scans for networks? I never had problems doing this before. I am using a cross over cable. Any one know what i'm doing wrong?
