I just completed my new LAN right here in my house, i have 8 PCs and 1 Mac Pro which i use a lot. I installed WoW (world of warcraft) and whenever i start it it crashs. This happend 3 times then i just used my pc. I have another Mac Pro which runs wow great without any problems. I thought it might be the RAM since i did buy them from an apple reseller but both of them macs have the same RAM and my finders (about mac) shows me my RAM is normal. WoW has just been installed there are not add-ons or mods its just a normal version.
