I just got my hands on a Feburary 2008 4, 1 Macbook for testing. I'm trying to figure out what OS is the max I can upgrade it to? I tried to Google search around but I'm not finding any good answers on it. Some say 10.6 is the last supported and some say 10.7.
Intel I7-2600k, Asus P8P67, 16GB DDR3 1600mhz, Geforce GTX 1070, ASUS Xonar D2, Samsung Evo 250GB, Western Digital Black 1TB, Corsair HX750w
