orsngepzr Posted February 25, 2014 Share Posted February 25, 2014 Hello everyone,a hacker from China;),so sorry for my bad English. After working days and nights for 3 months,i have installed 10.9 successfully and make the most part of it work perfectly! However,the f**king double Graphic Card design made it very hard for my OS X to get a long life without charger and alow temperature. I have tried a lot,i know the codes to disable Radeon 8730m is Method(SGOF) in ssdt-3 and Method(_OFF) in ssdt-4.But i just don't know how to use it... Here's my Hacking project: Product Name: SAMSUNG 730U3E/740U3E Operate System: Windows 8.1 Professonial X64( DirectX 11 )+OS X10.9 CPU: i5-3337U @ 1.80GHz MotherBoard: SAMSUNG_NP1234567890 (Ivy Bridge - HM76) Memory: 6 GB ( SAmSUNG DDR3 1333MHz ) Hard Disk: Samsung MZMTD128HAFV-000 Graphic: AMD Radeon HD 8500M/8700M(device ID:0x6601)+HD 4000（work perfectly by clover） Display: CMN1343 (12.7inch) Sound Card: ALC269VC Netwok Card: RTL8168E+AR9285 I have already made a DSDT and patched some necessary codes such as DTGP、SHUTDOWN etcs. There's no option in the BIOS to disable ATI. Thanks a lot if anyone can give any advics or help!

pokenguyen Posted February 25, 2014 Share Posted February 25, 2014 Copy all the files to your /EFI/Clover/ACPI/patched folder (if you have Clover). Set dropOEM SSDT=true in config.plist, then install kexts here: https://bitbucket.org/RehabMan/os-x-acpi-battery-driver/downloads https://bitbucket.org/RehabMan/os-x-acpi-backlight/downloads samsung.zip Link to comment https://www.insanelymac.com/forum/topic/296347-helphow-to-disable-ati-radeon-8730m-by-patching-dsdt-from-ssdts/#findComment-1997230 Share on other sites More sharing options...

The big problem is that i can't boot with your dsdt,ssdt,ssdt-1,ssdt-2,it shutdown suddenly in -v mode.Then i replaced your ssdts by my own ssdt,then it stopped at AppleLMUController:smcReadKey received error 0x84 when reading key MSLD.i will change the SMBIOS to MBA5,2(MBP8,3 currently) then try again.

pokenguyen Posted February 25, 2014 Share Posted February 25, 2014 What is your ig-platform-id? I changed it to 0x16600003.

orsngepzr Posted February 26, 2014 Author Share Posted February 26, 2014 What is your ig-platform-id? I changed it to 0x16600003.

daxuexinsheng Posted March 27, 2014 Share Posted March 27, 2014 Hey,Why don't you post to YuanJing forum? Well,I have done these jobs: 1.I remove the associational PEGP code to dsdt. So,you shouldn't use original ssdts now.Just because I remove necessary code to dsdt. You can use another way for power management. eg,CState and PState,or ssdtPRGen.sh. 2.Then,I call _OFF Method in Methond(_INI) and Method(_WAK).Usually,it should be worked. 3.I use ACPI 4.0 compiler to compile it. 4.And I think you shouldn't use dsdt to inject your HD4000.Just because your Method(_DSM) in Device (GFX0) is complex. 其实你在远景发帖也可以吧。 :-) DSDT_Disable_Discrete_Graphic_Card.zip Link to comment https://www.insanelymac.com/forum/topic/296347-helphow-to-disable-ati-radeon-8730m-by-patching-dsdt-from-ssdts/#findComment-2007862 Share on other sites More sharing options...
