Just made a successful boot with your EFI!
And the most curious thing, I forgot to edit the RAM (just copied to the USB pen and ejected it), and it booted.
I formatted my ssd, but now I'm having trouble with the installation. I can't boot to Clover after the first installation run. It keeps going to the installation menu of high sierra.
EDIT:
Strange things happened. As mentioned above, something happened to my clover boot pen drive after the first run, which prevented me to boot to the clover menu, so it kept booting automatically as it was always the first time (went to the menu that has the disk utility, install, etc, options).
So, today I formatted my pen drive and rebuilt it with unibeast 8.0.0, and my idea was to try the whole process from the beginning. But to my surprise, the clover boot menu now showed up and recognised my macOs installation, and I could boot from my SSD now and finish the macOs high-sierra installation.
In the memory information menu, it tells me the system has 3 memory slots, and that only 2 are used, for a total of 16Gb. This is also strange (I used the slot 0 and 2 on config.plist), but if I manage to optimize my installation with Multibeast, I think I'll stop here for now and won't try to understand what happened here. Maybe I'll try a fresh install in a month or so. I'll keep you updated.
EDIT 2:
Back to the ++++++++++ boot freeze after trying post-installation with multibeast (followed
this guide).
I believe this is probably because the pen drive used was the one created today with unibeast, and without
@materiks EFI copied.
When I have some more spare time I will try to redo everything and try to find why I couldn't boot from clover after first run with
@materiks EFI.
