In 2011, my iMac was sent to hell for a crime it most probably did commit. This Mac promptly crashed and caused the destruction of my WD 1tb External HDD containing my recently backed up files. Today, the iMac will not boot up, it is holding its head in shame on my desk.. ...I have a serious problem, if somebody can help, and if you can find the time, maybe I can call... The iTeam. Dah doh dah dohhhhhh! Doh dah doh!
