Quote from John098:
seems my laptop has 3 antenna cables... a black, blue and grey cabled one. Does this mean I have a 'Penryn/Santa Rosa MacBook' and do I need to look at a different guide..?
on the back cover there should be in small print that should tell you the model type of ur mac. its right between the two screews and shouldnt be that hard to find unless you somehow scratched it off
