First of all, thank you so much for this post shilohh. I followed your build closely and had almost zero problems getting my hack up and running.
I want to point out that there was an issue creating the ssdt.aml file. The script would attempt to download iasl from github, but would not be able to. I went through the code and found a link to where the file should be. I had to download the RevBoot zip and then pull the iasl file out. Then, I used the terminal to copy it to /usr/local/bin/ Once that was accomplished, the ssdt.aml file compiled without issue. How can I get word to Piker-Alpha to let him or her know that the script needs an update?
This machine is a screamer. Thanks again for posting.
