I have installed a new optical drive and keyboard. I have also upgraded to a 1 terabyte SSD. I have been trying for a couple days to upgrade the operating system. Unfortunately it will not operate with OS X 10.14 Mojave. What is the latest OS I can use on this machine? Also where can I acquire it? I am now running Snow Leopard
i know 2010 you can go with 10.13 but lower than that gonna be 10.11 or 10.12
