Green Apple of Doom on Start Up
This usually occurs when My MacBook Pro (15", early 2011) freezes up.
I'm forced to hit the on/off button, screen goes blank, and when I hit the on/off button again and it begins its power-up, the entire screen has a green-corduroy appearance. Instead of a solid grey apple appearing, a green-corduroy apple appears.
After the crooked, disjointed looking, green-corduroy load-bar loads, a white screen appears and the computer is at a standstill. If I do nothing, it will turn off on its own and attempt one restart. The same sequence of GAoD repeats, and then the white screen just lingers forever, and I have to hit the on/off power button to turn it off.
If I didn't enjoy puzzles, I would have thrown my MacBook Pro out of a second floor window, yelling "I'm mad as ****, and I'm not going to take it anymore" a long time ago.
I have found ways to solve the GAoD, but it seems to be hit or miss.
My worst nightmare of solving-disability came when I had the WiFi up and running, with Mail and Safari open, I was browsing a website, and I decided to click on Photos on the "dock."
I thought I'd never get the MacBook to run properly after that. But I did, and it was a miracle of perseverance on my part. (six hours of non-stop trial and error)
Whenever I have run the Diagnostic Testing, even Extended Diagnostic Testing, the result has been no problem found.
Currently running macOS High Sierra.
In my experiences of troubleshooting this mac, I have seen the most bizarre screens show up. They're indescribable: patterns of black/white diamonds (whole screen), the grey apple being grey in the middle, and fringe red on the left side (corduroy) and fringe green on the right side (corduroy), a entirely blue screen, and sometimes just weirdness that is too hard to describe at all.
My current solution comes after SMC reset, NVRAM reset, and then command+R, and keep holding it down, until a blue screen (sometimes dingy blue, other times bright blue-blue), which is the end of that individual attempt. Then it is on/off button, turns off, wait 10 — 30 seconds, and then command+R and hit the on/off again briefly, and continue holding down the command+R buttons until the blue screen, and so on, and so on. Finally, I'll get lucky and the grey apple will appear.
(I've even made a balsa wood "tool" (out of old model rocketry fin-balsa-stock) that allows me to place the glued together piece on the keyboard, and when I place a small weight on it, it depresses both the command and R keys, only, simultaneously, so that I can do other things rather than sit holding those keys down for the slow load of the green-corduroy load bar.)
Things I've been using are:
command + R (on/off); do this and just hold it down until a blue screen appears, which is the end of the attempt
option + command + R + P (on/off button, and let chime/start 4 times) resets NVRAM (nonvolatile random-access memory) and resets PRAM (parameter random-access memory)
shift + control + option (on/off button, hold down and count to 10);
resets SMC (system management controller); fans, lights, etc.
Last Resort: option + command + R (on/off; goes to spinning globe, then follow instructions)
command + S; doesn't do much
on/off + D for diagnostics; doesn't do much
I still believe there must be a precise sequence of trouble-shooting ideas to bring my computer back from the GAoD, and that's what this thread will be about.
