I have a question about my 10.8.5 Macbook Pro (Mid-2012), which has a default Intel HD 4000 graphic card. Recently, I purchased an external graphics card (NVIDIA GeForce GTX 650 2048MB GDDR5) and fixed it to my PCIe expansion chassis, which is properly hooked up via my thunderbolt connection and running. However, my laptop (hooked up to an external monitor) doesn’t recognize the eGPU. For example, under the "Graphics/Display" section in "System Properties" in "About This Mac", it does not list my eGPU. Is my Graphics Card compatible with my Macbook Pro? If not, then do I have to tweak certain settings as a super user in terminal in order to make it work? Or do I have to upgrade to Yosemite and use the method that you have prescribed? Or do I have to purchase an entirely different graphics card?
