I just bought a 2007 mac pro on ebay, not knowing the hardware was unsupported. Needless to say, I can barely install anything. I've watched a few videos and read a little, but everything I'm finding suggests installing something (like Parallels). Well, the problem is...I can't even install Parallels! I get the error "You have Mac*OS*X 10.6.8. The application requires Mac*OS*X 10.7 or later." Fantastic! Is there anything I can do other than throw this glorified web browser in the dumpster?
