Update sierra with no battery, only ac adapter.
So I just formatted my mac OS version 10.7.5.Downloaded sierra and launched it. Computer restarts and everything goes smoothly until.... "your computer is not connected to a power source ".
My ac adapter is attached but I have no battery installed, I intend to buy a new one soon enough but, I need to work in the mean time so.... Anyone could help me out?
Questa è una buona domanda?
