I have a macbook pro, and lately I have noticed that whenever I go on youtube or watch movies, the fan is very loud like it is literally going to explode. So one day I just closed my macbook and when I opened it again the screen was black, but it was still on. Tried booting it again and it was still black, it chimes and everything sounds fine except it is just black. Before I go in to get my macbook fixed I want to transfer files over to another macbook, not a macbook pro. The only problem is, is that there is no fire wire on the newer macbook. Is it possible plug in the macbook using a usb to an external hard drive, and then attach the macbook pro to the external hard drive and then boot it up and it will show up as an external hard drive??? I've tried this but no luck with the macbook pro showing up, do I need to hold down certain keys for it to show up??? Thanks!
