I finally called parallels and discovered that I needed to purchase a Windows 8 and download the disc into the program. I did and first my computer froze on me. After I restarted it, I was told that it can't find an operating system and something about disconnecting other systems. Am I missing an operating system? Should I have looked at what kind of Mac I had before I spent money on these two programs? It appears that not all Macs are compatible to Parallels.
