[Solved] - DSDT - MacIASL does not allow me to apply the patch

[yigitkerem]

Hi I've been following your guide on Fixing The Brightness Keys with BRT6.
I have created the following origin folder and opened SSDT-10-Sfgh.dsl and DSDT.dsl clicked patch pasted following but apply button got disabled.
If somebody can patch or can tell me what the problem is I'll be really happy.

into method label BRT6 replace_content
begin
    If (LEqual (Arg0, One))\n
    {\n
// Brightness Up\n
        Notify (^^LPCB.PS2K, 0x0406)\n
    }\n
    If (And (Arg0, 0x02))\n
    {\n
// Brightness Down\n
        Notify (^^LPCB.PS2K, 0x0405)\n
    }\n
end;

No BRT6 method found in your DSDT. This is why you cannot apply the patch. Attach your IOReg to check.

How do I add it? And I don't know how to attach IOReg either.

Use this link to download the IORegistryExplorer and once you opened the app from the File menu select "Save" and then compress the saved file and post it here.

It did not have an extension so I had to compress it.

Your IOReg is corrupt. Use IOReg v2.1. However, i checked your IOReg using v3.0.2
The reason you're not able to apply the patch cause you're using BRT6 which doesn't exist in your DSDT. Your DSDT uses KBD0 instead.

The keys are Q1C and Q1D. So the patch would be this.

into method label _Q1C replace_content
begin
// Brightness Down\n
Notify (KBD0, 0x20)\n
end;

into method label _Q1D replace_content
begin
// Brightness Up\n
Notify (KBD0, 0x10)\n
end;

And your Brightness Hotkeys should work accordingly.

So I open DSDT.dsl with macIASL click patch paste your code click export as ACPI Machine language and put the final file in CLOVER/ACPI/PATCED in EFI right that simple?

Oh YEAH! That Simple!
final code

And your Brightness Hotkeys should work accordingly.

And sure it does!

Done with the jokes but I might have missed a point in your article.

Your files have embedded External opcodes. No need for -da.
Disassemble with: iasl -dl DSDT.aml SSDT*.aml

Maybe Rehabman did not help a lot

Not mine but

https://www.tonymacx86.com/threads/solved-disassembling-acpi-could-not-parse-external-acpi-tables-ae_already_exists.265886/

got the same error.

So I had -da argument removed while decompiling it. It may help.

Yes, correct.

Yes, i already mentioned the same as a Notes in my guide. Credit goes to Rehabman. I've just made it simple to understand it more better.

I hope you can compile the DSDT as when i compiled, there was no any error.
