This mac was repaired 7 months ago by Apple with a (hopefully) new logic board replacement. It has since died whilst operating google sketch up software. Not a complex model and no high quality 3D renders were being processed, it just shut off with no warning. The only sign of life left is the charging light on the Mag charger. [br]
It has not responded to any combination of shift+ alt + ctrl + power, ctrl + R + power to reset system management. [br]
Anybody got any ideas what’s wrong with it?
