I appreciate your good intention to help me, I understand that you want to help me because you keep responding to this thread, however, I would like you to know that you are not helping me with your answers.
My knowledge of both English and programming is limited, I followed all the steps of the guide and I could not even start the installer, the only way was to add the "NullCPUPowerManagement.kext".
What am I supposed to do when you just respond to follow the guide? If I ask you to explain how to solve certain things, it is because I already try to follow the guide and I can not do it.
I am a musician, I work with that, I told you that I needed the MacOS for my work, because without Logic Pro I can not work, following your words I destroyed all the system I had, it worked badly, but at least it worked, now the days have passed, not I'm working, I'm just trying to follow your guidelines, and now all you're doing is answering that I should follow the guide.
I expected more willingness on your part the truth ...
If you do not have the time or the disposition to help me, I ask you to let me know, so at least I keep the High Sierra system that I have now, which at least works, to start working again.
Thank you!
