Salve a tutti,
ho un PowerMac G5 DP 1.8 GHz del 2003: a volte la macchina non parte, e il led frontale lampeggia 3 volte.
Ho provato a cambiare i banchi RAM (Perfettamente funzionanti e testati con memtest su una macchina X86).
Tenendo premuto il tasto di accensione per piu di 10 secondi la macchina emette un suono e poi successivamente parte.
L'Hardware test, effettuato con il disco ASD 2.5.8 di Apple mi conferma che è tutto regolare.
Oggi sono riuscito a farlo accendere ed è andato in Kernel Panic (a volte rimane bloccato senza alcun messaggio di errore)
ecco cosa riporta il log
