Apple have never once had the back of the professional 3D market, even though many of us have stuck with the platform and hardware, and used it successfully for 3D for decades. If it weren’t for the classic Mac Pro, and typically the 12 core option, i suspect most of us would have jumped ship many years ago. It’s testament to the build quality and flexibility that one Mac design had, that kept it in daily use for many of us, some 7-9 years after its release. This Mac Pro has now reached ‘Vintage’ status in the US, whilst for the rest of the world it’s classed as obsolete, so this really is the end of the road for these machines in terms of future OS support, even though I suspect some of us will still hold on and use them for as long as our frustrations can be tolerated!
That said, unless the new Mac Pro 2019 has ALL the flexibility of a modern PC, regardless of the design and build quality, I can’t imagine too many 3D pros will go for it compared to what I suspect will still be a significantly cheaper PC build. We could be amazed and shocked, but lets be honest, Apple has been lacking innovation, and still increasing their profit margins enormously for a few years now. I still love the Apple products I have and use, but I have absolutely no love or respect for the company they have become.
