Resolve won't run on that machine as the GPU is not supported by Resolve. You need a GPU that can do CUDA processing like a GeForce GTX card.
Mac minis are not supported nor are any Mac running Intel HD integrated GPUs (HD3000/HD4000).
Resolve also runs on some Macs with ATI cards.
If you want to run Resolve on Mac OS your best bet is a current Mac Pro, a new iMac, MacBook Pro Retina or wait for the New Mac Pro.
Alternatively you could look at building a Hackintosh:
