I installed 10.12.3 with this guide. After complete, except sound everything is OK. I tried to boot without cache but can't find the option on the Clover boot screen. I bypass and rebuild cache with this:
After the first restart, sound still be disabled, screen lose brightness
After the second restart, sound is OK, screen still lose brightness
I tried to reset EC but no changes.
I re run "./install_downloads.sh", "./install_acpi.sh", "ssdtPRGen.sh" but I lose sound again and screen still lose brightness.
What did I do wrong and how can I fix this?
