Moderators Jake Lo Posted July 10, 2017 Moderators Share Posted July 10, 2017 Brightness doesn't with AppleBacklightInjector (Brightness Slider work) You might have to change the Fn key to work. See my E7470 guide under post install. I use an app Karabiner Element to change the Fn keys to match what's on the keyboard. For HDMI audio to work, you need to determine which port to patch. Plug in an HDMI video, launch IOReg and save the file, attach it here for review. IOReg IORegistryExplorer_v2.1.zip Link to comment Share on other sites More sharing options...
