imac keeps crashing
Since 06:38 hours yesterday my imac keeps crashing. The only updates have been from Apple and AVAST but it seems that whenthe mac tries to do a back-up it crashes. The remote device is avasilable, accessible and ready. It is accessed vias wi-fi which is strong in signal, stable and I am using the mac when it crashes....
