Yes, that's what I thought. Anyway thank you!
I came to this answer after reading that it's unsupported on the FAQ, my question is, why is it unsupported on MAC and not on Windows? I have a Macbook Pro Retina, I see that it has 1500mb of video RAM with the Intel 4000, which surely would seem enough. I know it's a really low end graphics accelerator, but, why is that it does work on Windows and not on OSx, will there ever work again? I consider it a bit of disservice to us who have Lightroom on our mac but can't upgrade it to a newer model. Will the Metal API be used on Adobe software?
