Fixed apple black screen of death, cursor top left log in after boot salamanda uk. [help] apple imac 27 black screen / screen of death problem - duration: 21:05. ohhh sssht 23,902 views.. Oh and the " black screen of death " is what people are calling it, not sure of the official problem name but it's an intermittent tendency of the display to go completely black while the os is running fine.. Doesn't time fly. i thought that my imac was still under guarantee, but it's well over 2 years old! today it died. at least i thought that this was the problem, but it comes back on after a reboot. further investigation shows that the computer is ok. it's just a black screen. i can access all the.
When you first turn on your mac, the screen is black and you hear a startup sound if your mac is from early 2016 and earlier. your mac initializes its bootrom and memory (ram). it then performs a power-on self test (post) and a bootrom test..
