I was innocently working on the Mac, tweaking a presentation in Keynote. I decided to insert the Software Install CD that came with the mini so I could install GarageBand, for the presentation. Right after I inserted the CD, everything went straight to hell! Every single tiny action takes a full minute or two to perform - simply clicking on a menubar item (in this case, File in Keynote because I wanted to save the presentation before things went even deeper into hell). I managed to save the presentation about like, 5 minutes of clicking File then Save, and alots of beachball wheels. I went to restart after successfully saving and quitting Keynote for good measure (which is insanely slow and beachball-filled). And the restart itself was shot to hell too - an incredibly long beachballing, then the elements of the Finder goes away leaving the wallpaper there. I waited and waited for the machine to actually restart, and finally gave up and hard-reset it. It's fine now, and the CD mounted with no problems after restart. It's like when I inserted the CD, the CD chokeslammed the mini right through the mat. Total KO! What the hell just happened!?!
