I ran both the gibMacOS command and the MakeInstall command as an administrator and still got the same error. I also downloaded the macOS version in recovery mode. I tried to install ddrelease64.exe manually by placing it in the gibMacOS-Master folder but I'm not sure if that is how you install it correctly.Did you run the script as administrator?
