Mac Pro is the ultimate machine for users who need to complete heavy tasks like rendering videos, photos and games development. But starting price for a Mac Pro is expensive. Some people try to find an alternative by creating their own machine running OSX and it is called Hackintosh. When you do Hackintosh, don’t call Apple support when your Hackintosh machine crashed and all your data is lost. It is because you are running their operating system on unsupported hardware.
If you want to buy your first Mac, maybe you can buy latest Mac Mini or an iMac and see how things goes. It may give you a better experience compare to a Hackintosh machine because you will have all the access to Apple ecosystem. But if you know what you are doing, do at your own risk.
