Hi One And All It appears my iMac 24"Early 2008 has gone to Mac Heaven. On returning from oversea's after six months i turned on my long serving and faithful mac only to be greeted by a white screen, then after a few minutes the apple logo, Great! Not so after a few more minutes what appeared to be a No Entry Sign, then nothing, nothing at all off! on! nothing! off on again nothing.....Damn it! off to the local Apple reseller, one of the disadvantages of living on a small island, only to be told some week and a half later that the Motherboard had gone and that there was nothing they could do as my beloved machine was that old Apple had stop making that part. Question, is this really so? Please help.
