Problema iMac che si riavvia? (crash)

[tanispectre]

Salve a tutti..è da almeno 2 giorni che il mio iMac da 21" ogni tanto presenta una schermata offuscata con al centro un quadrato nero con scritto nelle varie lingue che è necessario riavviare il computer tramite il tasto dietro dal pc.
Non capisco perchè, e quando vado a vedere il resoconto al riavvio mi dice che il problema è stato per il LAUNCHD, o per FIREFOX-BIN
Qualcuno di voi sa di cosa si tratti?
appena risuccederà incollerò tutto il resoconto qui, magari a qualcuno è gia successo

[tanispectre]

ecco il resoconto che mi da
