I’ve a Macbook Professional Retina 13″ Late 2012, with macOS Mojave / Ubuntu 24.04 twin boot put in. A number of days in the past, whereas utilizing Ubuntu, immediately, the display screen was striped black and white. I pressured restart, and first, the Ubuntu startup show was proven, however earlier than login, it turned striped once more. Then I booted from macOS, which labored tremendous, even studying a PDF labored, however immediately, the higher half of the display screen was striped the identical approach, the decrease half labored for one more minute, till the display screen slowly pale darkish. Since then, the show stays completely black, not even exhibiting the startup display screen (Apple or Ubuntu with progress indicators), startup quantity choice display screen (‘choice’ at startup), or any background gentle – completely black.
The whole lot else works tremendous in each OS. Sound works, and I can usually function the macbook with an beamer (do not have an exterior monitor). Even the inner Webcam works (I attempted it with Photograph Sales space), and after I shut the lid, the macbook goes to sleep. (Simply the illuminated apple signal on the again doesn’t work).
Here’s what I attempted:
- checking energy provide, charging battery, limitless variety of pressured and regular restarts, ready a number of days, adjusting brightness…
- Secure Mode (‘shift’), SMC reset (‘shift+choice+ctrl+energy’), NVRAM reset (‘cmd+choice+p+r’), Single-Person Mode (‘cmd+s’), Booting in Restoration Mode – the whole lot works as anticipated, however inside show stays black.
- Working Apple Prognosis (‘d’ at startup) – there, it says ‘Error: Can not Load EFI/Drivers/TestSupport.efi’
- shaking the macbook a bit (I discovered this on-line, to repair unfastened connections inside)
‘About This Mac > Show’ exhibits ‘EPSON PJ’ (the beamer, I suppose) when the beamer is linked, and ‘Intel GPU’ as graphic card. After I disconnect the beamer (take a screenshot and think about the screenshot by connecting the beamer once more), it exhibits ‘Inside Show, 13,9″‘, however with none GPU.
Now I do know, it is a very previous macbook, however till now, the whole lot labored tremendous. I even put in Ubuntu every week or two in the past, to get safety updates and hold utilizing the macbook, as it’s nonetheless quick and really usable. May the twin boot/Ubuntu be an issue? Or is it only a unhealthy coincidence that the show broke shortly after the set up?
Does anybody have another thought what may be the rationale? And the way to repair it? Ought to I strive a recent set up? Or opening the macbook and checking the inner connection?
Should you’d say the show is damaged and the one approach could be changing it, the place can I discover a low-cost alternative show? Would you say it is price it?
