A Beginner's Guide: How to Patch AppleHDA for Laptops


New member
ACPI isn't patched correctly. You must patch them correctly. Some invalid kexts are being used along with improper configuration.
Its probably not the patching process (how) but what patches I have used or not used. Same with the config or kexts. I am a bit lost there. Everything else seems to be working fine. Please give me some more clues - what patches should I use? anything specific in the config? what kexts are invalid?
