I'm getting a completely black screen any time I log into my MacBook. I enter login details and hit enter. It was getting about half way through progress bar displayed after this and then screen just goes completely black.

This all started when my laptop randomly went black while logged in the other day and browsing Facebook via Chrome.

I’ve tried all options (SMC and PRAM reset) from this article but none seem to work. I'm actually getting the black screen on boot up sometimes now too

I tried hitting the reset password using Apple ID on login screen also but now I'm just getting the progress bar in boot up and it also goes to black screen after half way.

Also tried holding the Shift key on boot to enter single user mode as per this quesion, it just quickly shows terminal options and then exits.

Can’t remember the exact model of the MacBook but I think it’s 2012 retina MacBook Pro.

Attached screenshot of trying to enter verbose mode with Cmd + v. It just quits this and goes to login screen after.

enter image description here

Managed to log in after hours of numerous attempts. Crashed to blank screen again after playing videos in Chrome. Allowed battery to run out during day and started up again tonight, worked first time.....no crashes yet!

Here is report log:

The only thing that stands out to me in that log is the line

Everything else just looks very Apple ordinary.

I'm not a pro yet, but considering you were also using Google chrome, which uses "Hardware Acceleration", pushing your GPU, I am definitely thinking you may have a gpu that's starting to go bad or become defective.

    I dropped into a compuB store who are an apple authorized service provider in Ireland seen as there is no apple store here. Helpful guy told me it will most likely be covered by Apple under ECLC consumer law (Up to 6 years from purchase). Filled out forms and left it with them, will have more info in few days.

So it’s getting repaired for free under ECLC even though 5 and a half years old!, happy days!

Here’s the report:
Issue replicated, running diagnostics
MRI failed on battery
Battery test failed
VST failed

Device needs a new logic board and a top case with battery under ECLC


There are a couple more basic things that you can try. First, create a bootable usb of mac os on another computer using createinstallmedia commands in terminal. You can find thos instructions here

Then insert your bootable usb of mac OS and hold down the control key until you get to a boot screen. Select your usb key "install mac os high sierra" on the boot screen, and hit enter. See if it loads to the installation screen. If it does, try reinstalling to the same drive without re-partitioning or formatting your drive. As long as you dont format, none of your personal data will be lost. You will just be reinstalling the core OS. Once installed, boot back up and see if your screen is fixed. If not, then it most likely is a hardware problem and not a software problem. Could be a faulty graphics card or something. But try reinstalling mac os forst and let me know how that goes.

  • I managed to fluke my way to logging in..not sure how I used so many different ways. Computer just randomly shutdown again later in evening when watching video using Chrome....I think that's what triggered blank screen first time also. I've attached the error report to orginal question, I wonder is Graphics card related as you stated? Is there a way to disable the card and just use the integrated one?
