I have a Mac G4 17" laptop with a bad logic board. I just bought a G5 tower with no airport card. I would like to know if the card from the laptop would work with the tower and if so how do I install it?
Contact you local Apple authorized Service Location (or Apple Store).
Now with the G5 it might be real simple. Just get an Apple Airport Extreme card (if your mac can take it since you did not tell what Mac you have) and pop it in.
