So I have an old PowerMac G4. I got it last summer from a family member who wasn't using it, and i haven't really used it since. The power cable is kinda messed up, it has trouble booting cause of that (i think), but when it does boot up it seems fine. Only issue is how do i go about getting it hooked up to wifi? Would i need some card, adapter, etc? I already have a 13" rMBP but hate to just let this old desktop sit around and be useless. Any ideas how i could get it up and running well again? --- Post Merged, Apr 30, 2016 --- An update: Just pulled it out and when i press the power button on the machine the light turns on white, but then fades out. If i press the power button the cinema display which is hooked up to it, that light on the display turns yellow but then fades out. It sounds like the computer try to start but then doesnt. BUT if i hook up the webcame via FireWire, it boots up? Why would it do this?
