Hello everyone. I appreciate when you spend time in my topic and help me solve this problem!. My MBP could not boot anything ( Internet recovery, CMD R, CMD V, shift…) I tried install fresh copy of high sierra but just grey screen with nothing on it? I did try single mode user then I got the screen like this
Can you help me with this problem.
This most likely happened when you upgraded to High Sierra. The problem is most likely with your SSD as Apple doesn’t like you doing 3rd party upgrades and has tried to imposed APFS formatting to the SSD drive. I would pull that drive reformat it GUID and only take the machine as high as Sierra.
