[Guide] Disabling discrete graphics in dual-GPU laptops

You cannot remove the entire method. You must move only the EC related code to _REG.

Yeah, that's what I meant, I was too lazy to write.

Must provide all files requested in "Problem Reporting" each time a change is made.
But by your own description above, you did it incorrectly.

The files are in the attachment.

You can see in ioreg that it is not working (and in System Information -> Graphics).

SSDT-11.aml has no call to _OFF from _INI.

Ok now I don't see the nVidia card in System information -> Graphics. Can you check I did everything fine?

Looks good to me. The ioreg shows it disabled and the correct code was moved to _REG.

Hi Rehabman,

I did succeed in 10.11. but after update the system to 10.12 , reinstall all of the patches and regenerate DSDT/SSDT, I failed even revert back to the original... Please give me a hand. thank you .

Read post #1, "Problem Reporting". Provide *all* files and output requested.

You did not patch ACPI correctly.
First, your files in ACPI/patched cannot be disassembled (iasl -da -dl *.aml). That is a bad sign (duplicate symbols).
Second, the wrong files are there anyway... you should have in ACPI/patched:
DSDT.aml
SSDT.aml (ssdtPRgen.sh)
SSDT-0.aml
SSDT-1.aml
SSDT-2.aml
SSDT-6.aml
SSDT-7.aml
SSDT-8.aml
SSDT-9.aml
SSDT-10.aml
SSDT-11.aml
SSDT-12.aml
SSDT-UIAC.aml (your add-on for USBInjectAll.kext configuration)

after regenerate ssdt.aml with ssdtPRgen.sh , rename SSDT-UIAC-All.aml to SSDT-UIAC.aml and remove SSDT-10.aml(SSDT-10 should be SSDT-UIAC-All.aml,I didn't notice that), ACPI/patched can be disassembled. but the issue remain the same.
For ssdt.aml was generated in 10.11 and I just copy it to the 10.12 . Do you mean that ssdt.aml must be regenerated when OS X is updated, pls?

Why did you add DSDT.aml to SortedOrder? SortedOrder is only for SSDTs.

SGOF (called by _OFF) has EC references that must be moved to _REG. Read the guide carefully.
