Dell Inspiron N3421 with Sierra 10.12

[dunhill_]

Hi experts,

 

I am sorry for my bad English and I am newbie of Hackintosh

 

My laptop is Dell Inspiron N3421 with configuration as bellow:

RAM 4GB

CPU Intel Dual Core i3-3217U, 1.8GHz
Display Hybrid Intel HD4000 and nVidia GT625M
Sound Realtek ALC282
WiFi Atheros AR9565
LAN Realtek RTL8100E

 

I use config.plist by Rehabman and collect kexts from many sources to install macOS 10.12 successfully on my laptop.

But the screen is always flickering, and I think that nVidia GT625M is not disabled.

I have read many times instruction by Rehabman to disable nVidia GT625M but I do not understand, it is very complicated for me to do.

Could some one please help me to patch DSDT and SSDTs to disable nVidia GT625M to reject screen flickering. Please see the attached pictures and EFI file for details.

 

Thank you very much
