Hey, I have a macbook pro, pre unibody version, Intel C2D, 4 gigs of ram. It's running Windows 7 on a separate partition. Recently I got a free copy of Windows 8.1. Enterprise through the Dreamspark program. Will it run fine on the mbp? For example, on Windows 7, I have no fan control, and have to adjust fans manually through a little program called macfan. How is the general experience with W8 and pre unibody macbook pro hardware support? Am I safe to upgrade?
