I can't get to my drive so I can't upload. If you upload your files, I'll try that. Please offer the step you took to fix.Check out my post:
I think your clover is old. I had this problem and it solved by updating it with the latest version.
I uploaded clover EFI. use that to boot.
my cpu is 6600K. If you won't be able to boot again, post here so I upload my own EFI and config.plist.
P.S. I was stuck at black login screen same as you, I reckon.
Hi there whats your System Defination ?Update via AppStore (after updating clover) went fine on an old Intel i5 and Radeon HD 7850, luckily no flickering and no graphic issues.
No NightShift but that was to be expected because of my old system definition (anyway I found f.lux to be way superior, esp. because of the slow changing to warmer levels, compared to the "binary" change of NightShift... so I'm not going to fiddle with my system definition )
