Mining I know that GPU is use to mine but in other case did someone did use a mac pro to mine?. The most expensive mac can mine?
I garuntee that you will loose your laptop very fast.
For the Mac Pro or any apple laptop, there is one big drawback is there. These machines don't have cooling fan and there is literally no space for the heat to exhaust out of the motherboard. If you did not notice it then just check that with your lappy right away. :-)
Why this concern anyway?
The reason is simple, with mining the network will use cores of your CPU and more heat is generated. This heat can be more than 60 degrees in very short period of time with no air circulation in your mac. So there is no question about putting your expensive mac at risk rather than getting cents or dollars a month.
