Ok, I think your setup def has the power to run Notes, but I’m worried that there might be some compatibility issues, especially with the chip and some stuff we have going on internally (AVX2) and maybe the graphics card. I’d love to be able to support the mac pro you have, but it might be that we spend a few days getting it going, it might not work and also not so many other people will have this exact setup, due to this it becomes super hard to have devs working on it without an assured outcome.
I can process the refund right now if you pm me your email address you used at checkout. Sorry about that and we’d love to have you as a customer and appreciate the fact that you checked it out.
