Chosen Solution
Screen will completely turn snowy static and will not come back. If I leave it and not touch anything the system will reboot. Some people have posted a similar issue for a High Sierra bug but this screen does not happen only on boot but persists until reboot. Please let me know if anyone has a solution to this or knows what I need to fix. Mid 2012 13” MacBook Pro running OS Mojave 16 GB RAM and Samsung 850 EVO SSD. I’ve reset PRAM, SMC, booted in safe mode, recovery mode, internet recovery mode, repaired disk in Disk Utility and in recovery mode, opened up the back and checked the RAM, checked the display through HDMI to external monitor, even pulled out the SSD and booted from an external enclosure through USB but it still will “crash and freeze” in this static snowy screen. I thought at first it was the HD cable as I’ve had to replace that before. Could this be a display cable issue? Or logic board/graphics card? Thank you and please help if anyone knows a fix other than replacing the logic board. I can’t seem to find any answers..
That doesn’t match with a faulty drive cable which is by default a suitable one on your Mac too. Snowy static makes me think more of a GPU or related issue..what does it happen when you plug to an HDMI external ? If you have the same issue there too a GPU related would be confirmed. However, I find it hard you can get out of it without a board repair or replacement.
