I already did search for some topics regarding this issue, along with multiple google searches and couldnt find an answer. I have a Mac Pro 1 1 with 18 gb of ram and an Nvidia 7300 gt. I have parallels 7 installed along with Windows 7 64 bit installed in a VM. I installed Starcraft 2 the other day and ran all of the updates available for both windows and starcraft. i have 8 gigs of ram allotted to the vm along with 2 cpu cores and 256 mb of vram. Heres whats happening. Whenever I try to load starcraft 2 it says something about the video card not being recognized or usable because it is locked. Sorry, not at home so can't remember the exact error. So I looked in the device manager and saw that the only graphics card within the VM is a "Generic VGA Grapics Adapter". My next thought wast to download the nvidia drivers for the 7300gt which i did. then i tried installing them and it said that there is no videocard in this computer that can utilize the drivers that im trying to install. Also, within the device manager there are 2 unrecognized pci express devices, so i tried manually installing the nvidia drivers to both of these but didnt work. Whats weird is the 7300 gt is the only pci e device i have in my mac pro! If anyone else here has run into this issue, please tell me how you corrected it. Thanks!
