Thanks for the quick reply!
When I tried running sudo mountesp I got:

sudo: mountesp: command not found 

When I'm eventually able to make the startup.nsh file, how big should I expect that file to be? That way I can have an idea if it's right or not. Also, I'm guessing this file is specific to each machine?

@tanukilandslide, mhh, did you do that in terminal in macOS? 🤔

For me it always works... 

maybe you must deactivate the SIP (system protection) in recovery mode after start by pressing CMD+R (Recovery). (I am not sure if this is necessary, but I am having it deactivated.)

then open terminal and type 

Csrutil disable

if you want know wether it‘s on or not type

Csrutil status

Startup.nsh is machine specific, but it matches fundamentally with the MacBook 15“ mid 2015.

The size? I will post next time, when I am in MacOS 😁

and if you run the Radeon VII, you will get a big chance that even this monster works great (delete all #), as you see in goalque‘s build.
