No safe boot into safe mode (Mojave,Catalina other?)

[JochiePiet]

Hi,

 

I have recently installed Mojave. Went flawlessly. Then I upgraded to Catalina 10.15.1. Went almost flawlessly as well. The only problem I have detected so far is a problem with the sleep/wake cycle. It is possible to let the computer fall asleep, but no wake up then. Hard reset required.

In the process of investigating I discovered that it is impossible to safe boot into safe mode. So I downgraded to Mojave, only to discover that the safe boot problem wast there too.

 

These are my specs:

Motherboard Gigabyte GA H77 D3H  rev 2.0

MacOS Catalina Version 10.15.1 (Build 19B88)
Kernel                         Darwin 19.0.0 x86_64
RAM                            4.00 GB
Model Identifier        iMac14,2
CPU                            Intel(R) Core(TM) i3-3225 CPU @ 3.30GHz

Intel Generation      Ivy Bridge

 

This is the output I get trying to boot with Clover and the bootflags: -v -x (I have also tried -v -x -f and UseKernelCache=no):

 

 

Thank you so much in advance!
