any corrosion on motherboard? In what humidify it was used? How it was used? (I talk about CPU/GPU usage) They do not die just like that - HAD TO BE REASON. Power on Mac without any drives - and WITOUT ANYTHING in USB - just video cable and power cord only! Tall me about those beeps - as they mean something - like 3 long 1 short etc.
I think (because MacBook is on so far for about few hours) - final release Mojave and clean install fixed problem. Crazy think - under clean Beta 11 I still had shutdowns - I kind-of-fix them with disabling Thunderbolt drivers. So far so good
Hello Berco Could You please tell me is Your MacBook working with “dongle” MiniDisplay cable/dongle in? I thinking to cut that DisplayPort cable and create dongle and live with it Does it work for You like this? Thank You :)
