Hello, new here. MacUser for long time, pulled the hard drive from my 1st gen MacBook and popped in what I thought was a blank hard drive, booted the machine. Had to take a phone call and when I returned, there was Windows 7 Ultimate sitting there, staring at me on my Mac! It installed all the drivers for the hardware, too. No Mac software installed on the drive (I've looked!) Has anyone else experienced this? However: I can't get a right-click function out if it. Does Microsoft know it can run a Mac without BootCamp; do the Parallels people know this? Does APPLE know this?
