Chances are, if you Mac is 2 years or older, you won't have an acceptable video card to run it.
It won't run on my 2008 top of the line Macbook...
Works fine on my 2008 bottom of the line iMac 😉 It is a high end graphics heavy program after all so the old integrated Intel video accelerator won't be able to run it. Don't feel bad I have a 2008 MacBook too but I bought it knowing it would never be capable of performing high end graphical tasks.
