Hi, I bought a thunderbolt display for my macbook pro 17'' early 2011 and it works great. But also I would like to connect my old white macbook(a1181) to it so my family can use it when I'm not at home. I upgraded the old macbook to 6GB RAM and 256 SSD, so the performance is quite good for casual use. I'm aware that max resolution for 2nd display is 1920x1200 but still I want to connect it, so they can enjoy this beautiful display. Will this cable do the job http://www.amazon.es/StarTech-com-Cable-Adaptador-MiniDisplayPort-Displayport/dp/B002XVYZ82 if not, any alternative?
