Since it looks like there are really no good guides to mine z-cash on a mac that has an Nvidia gpu, or a hackintosh with Nvidia, I decided to write one myself on my blog. In addition, I cover ways to automatically start mining every time your macintosh/hackintosh boots. Hopefully this will help the small pool of mac users wanting to mine zcash not feel so left out. Anyway, the link is here: https://nerd-tech.net/2018/05/27/how-to-mine-z-cash-on-mac-os-with-a-hackintosh-with-an-nvidia-1080gpu/
