Ok so i just bought a ps3 a couple of days ago and i was wondering since the wireless in the ps3 doesnt connect to my wireless at home if there was a way to set up internet sharing via my macbook to connect my ps3 to the internet. would i use an ethernet cable that is plugged into my macbook running out into the ps3? If anyone knows how to set this up or just set it up in general please tell me thanks!
