MacBook doesn't boot after Mojave Update
After updating to mojave, a friends macbook doesn’t boot anymore. First it did but the touch bar wasn’t working. After that, it didn’t boot anymore. The backlight is turning on but no feedback from the macbook, no chime, no beep, no apple logo.
I tried a lot of short cuts already (NVRAM and SMC reset) but since there is no feedback at all, it seems like the commands are not getting executed at all.
Currently I just let it run with the backlight on so the battery gets discharged.
I could open it and disconnect the battery but I don’t neccessarily want to remove the tapes on the battery cables if possible.
Anyone here experienced this or has a suggestion? The next genius bar is 2 hours away and I don’t have a car.
