<< Solved >> Doesnt boot anymore after update / EFI doesnt mount

[Raicoko]

Hello,
I have installed 10.13.6 onto my system and it worked very well for more than 3 years.
Then after a classical switch-off of the computer I try to switch on again and it doesnt want to open anymore.
The opening goes after the clover but before the apple logo. Hopefully I succeed to boot with "safe mode"... Do you have any Idea how to solve this issue?
I never do update of my system but I may have clicked on this kind of option by mistake.
Because on the verbose mode I've read :
(pid 42 sel : 7 ret : e00002c2 '-536870286', --1, 100000)

Also, I've tried to mount the EFI partition with clover configurator and it doesnt succeed..
Even with command lines (
User-iMac:~ User$ sudo diskutil mount disk0s1
Password:
Volume on disk0s1 failed to mount
If the volume is damaged, try the "readOnly" option
User-iMac:~ User$ )
Here some screens of the verbose mode :

Thank you so much for your help

Hi there.

This looks like a recently discovered issue with the Nvidia web-drivers.

The app’s authorization has been revoked (High Sierra NVIDIA graphics certificates expired)

I just reset the NVRAM on my High Sierra Install by pressing F11 at Clover boot menu. It rebooted automatically, then booted using my GPU. Tried opening the nvidia download package from downloads page here, (which I used dozens of times). Now Im getting an The app’s authorization has been...

There are now new drivers to get around the issue. The zip file is in the thread.

Do you have ideas?

Install these drivers that are signed. https://www.tonymacx86.com/threads/...hics-certificates-expired.320609/post-2326893

You don't have to do anything with the EFI.
