I have just purchased a MAC Quad for my photo work and will move PS and PM to this machine. Do I need to buy a new copy of PM for the MAC or is there a way to transfer my Windows license to the MAC ?
Just re-enter your registration info on your new Mac. That's all there is to it.
Now if you want two people to use Photo Mechanic on both systems concurrently, then you should purchase another license. If there will never be two separate users using Photo Mechanic at the same time then a single license is OK.
