I'm at the point where I've edited the plist but haven't added the kexts, I boot up the installed OSX and run multibeast, select HD530 graphics, and install. Everything works fine until it gets to the HD530 installation at which point it fails. The logs don't provide much help (can't get them in entirety because my mac has no internet yet):
install.log:
Install Failed: Error Domain=PKInstallErrorDomain Code=112 "An error occurred while running scripts from the package "Clover-HD530-Graphics.pkg"." UserInfo={NSFilePath=./postinstall, NSURL=file://localhost/Volumes/USB/Multibeast.app/Contents/Resources/Clover-HD530-Graphics.pjg, KInstallPackageIdentifier=org.tonymacx86.Clover.HD530-4-Displays.pkg, NSLocalizedDescription=An Error occur... etc
Multibeast.log has nothing that the above doesn't.
Any idea why this is happening?
