I have the black screen on my Mac Mini and have tried every solution possible from the web but nothing has worked.
All I get is the Apple logo with the loading bar then it goes to black screen.
How can I restore from a backup if I can't get to anything to start the restore?
The only thing that I can get to is the command prompt (white text on a black screen)
Mac mini, macOS 12.1
First, Which Mac Mini?
Second, could you list the solutions you have attempted, just so we don't repeat them?
I'd suggest working your way through the startup-key combination list. Mac startup key combinations - Apple Support
In particularly, does Startup Manager, Safe Mode, Apple Diagnostics, or Recovery work?
A lot of other people are having this issue after updating to macOS 12.3. The problem seems to be if you are using thunderbolt/USB-C for display and are using scaled resolution. The fix/workarounds is to connect display via HDMI. From there you could change your display resolution to a non-scaled resolution, then change back to thunderbolt/USB-C. Once everything is running you can change your resolution to a scaled resolution, but when you restart you are back to black screen. Wake from sleep works, so don't turn off your computer unless you want to do the cable dance. |

Hi, It is a Mac Mini Late 2014 Intel i5
It has latest Monterey OS and was running fine with that for weeks.
I have tried all the suggested..
Hold down command + S + P + R
Hold down Command + Opt + P
Hold down Opt and start Mac
The only one that produces a screen is the following but then the commands after that just show file not found errors.
Hold command (⌘) + S while powering on
command prompt ( :/ root# )
/sbin/fsck -fy
/sbin/mount -uw /
rm /Library/Preferences/com.apple.loginwindow.plist rm /Library/Preferences/loginwindow.plist rm /private/var/db/.AppleUpgrade
How do I restore from backup which I have if I can't access any disk screen?
Can I restore from backup from command prompt Hold command (⌘) + S while powering on?
I don't think the first two key combos are actually commands...
Give option a second try, only this time shutdown the mac first and begin pressing and holding option a split second -after- you power up your mini.
If that doesn't work try:
<command-r> for recovery mode, or <option-command-r> for internet recovery.
If the first fails the internal drive may be dead or corrupted. If the second fails I'd wounder if the 'option' key was broken.
I have exactly the same issue. SMC and PRAM reset does not work. Booting into Safe Mode displays the desktop like it should do, but it is in safe mode. Recovery Mode works, too, but Disk Check does not find any errors and Reinstalling macOS without deleting does not help either.
Update: managed to get to the <command-r> for recovery mode... then
Tried to restore a new copy of Monterey, after completed still same black screen.
Now trying to restore from a TimeMachine but get the error about BaseSystem.dmg does not contain a APFS volume.
I read somewhere on macRumors, that it could help to change the DisplayPort version on your monitor from DP 1.4 to DP 1.2. I tried that, but with that, my Mini does not want to boot at all, and is stuck on the apple logo with the progress bar, with the progressbar not going above 5%.
Apparently going with HDMI is a workaround, i ordered a HDMI cable suitable for 4k, and will check tonight.
