  1. Edited the 15/07/2014 Hi all ! After months of passive research i have found on some different forums a DSDT solution for disabling the NVidia card. Disabling Nvidia allow to save battery power of 2x and temperature of laptop too. My Specs Acer Aspire V3-571G-73614G50Makk :: Processor Intel Core i7-3610QM 2.3 GHz (Intel Core i7) :: Mainboard Intel HM77 (Panther Point) :: Memory 4096 MB :: Graphics adapter NVIDIA GeForce GT 640M - 2048 MB, Core: 708 MHz, Memory: 900 MHz, DDR3,, Optimus :: Display 15.6 inch 16:9, 1366x768 pixel, LG Philips LP156WH4-TLA1, TFT LED :: Soundcard Realtek ALC269 @ Intel Panther Point PCH - High Definition Audio Controller :: Networking Broadcom NetLink BCM57785 PCI-E Gigabit Ethernet Controller (10/100/1000MBit), Atheros AR5BWB222 Wireless Network Adapter (b g n ), 4.0 Bluetooth :: Optical drive MAT{censored}A DVD-RAM UJ8B0AW :: Hackintosh Config SMBios : Macmini6,2 org.chameleon.boot.plist : link DSDT : link Extra Folder : link Source DSDT/SSDT Method ( work on it, not fully fonctionnal ) : Link here DSDT Method (work with all bootloader) Instructions Needed AIDA64 version 2.80 --> link ssdtPRGen.sh --> link AppleIntelCPUPowerManagementInfo.kext --> link MacIASL --> link Disabling NVidia card In the first step, dump your dsdt from Windows with AIDA64 (version 2.80 max) --> tuto YouTube Reboot on OSX This patch don't need to extract or modify any SSDT. You can see the DSDT edits in the link of qwerty12 topic in credits. Quickly, in DSDT, i call external method for disabling the card. These links calls methods of SSDT-4 in my config but can be different with your machine. You don't need to copy manually the _OFF method from SSDT to DSDT. Add these lines if you don't have them to the top of your DSDT : [...] External (_SB_.PCI0.PEG0.PEGP._PS3, MethodObj) External (_SB_.PCI0.PEG0.PEGP._PS0, MethodObj) External (_SB_.PCI0.PEG0.PEGP._OFF, MethodObj) External (_SB_.PCI0.PEG0.PEGP._ON, MethodObj) External (_SB_.PCI0.PEG0.PEGP.SGOF, MethodObj) External (_SB_.PCI0.PEG0.PEGP.SGON, MethodObj) [...] I added the method M_OF before the _WAK method : [...] Method (M_OF, 0, NotSerialized) { If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._OFF)) { \_SB_.PCI0.PEG0.PEGP._OFF() } If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._PS3)) { \_SB_.PCI0.PEG0.PEGP._PS3() } If (CondRefOf(\_SB_.PCI0.PEG0.PEGP.SGOF)) { \_SB_.PCI0.PEG0.PEGP.SGOF() } ​ } [...] After that, i call the M_OF method in _WAK : [...] Method (_WAK, 1, Serialized) { M_OF () If (LAnd (LEqual (\_SB.PCI0.LPCB.EC0.AAST, One), LEqual (\_SB.PCI0.LPCB.EC0.AAEN, One))) { Store (Zero, GP53) [...] And i call the M_OF method in the _INI method : [...] Method (_INI, 0, NotSerialized) { Store (0x07D0, OSYS) M_OF () If (CondRefOf (\_OSI, Local0)) { If (_OSI ("Windows 2001")) [...] If you use Chameleon or branch, paste your modified DSDT to your Extra folder and add these options to your org.chameleon.Boot.plist : <key>DSDT</key> <string>/Extra/DSDT.aml</string> <key>DropSSDT</key> <string>No</string> If you use Clover Bootloader, copy DSDT file in "EFI/CLOVER/ACPI/Patched" Reboot and go to Applications/Utilities/System Information Go to Graphics Card Section, if the NVidia Chipset not appear, it’s working. Enable the SpeedStep management The only problem with this technic is the Power Management. When your turn off the DropSSDT flags in org.chameleon.Boot.plist, Chameleon don’t go dump your SSDT tables in the ACPI tables of your machine. For enabling SpeedStepper with that fix, you should make a patched SSDT with the ssdtPRGen method : Download the later ssdtPRGen.sh Be sure that your SMBios.plist is appropriate with your CPU and system (A good SMBios can fix the iMessage, iCloud, iTunes and Apple Store connexion and login bugs). With my V3-571G core i7, i prefer the Macmini6,2 model for more speed steps. In Terminal app, launch the ssdtPRGen.sh with command : sudo sh /the_way_of_your_file/ssdtPRGen.sh Write your password and type "y" when it’s demanded for make a ssdt_pr.aml in your Extra folder only if you use Chameleon bootloader. If you use clover, copy this file in "EFI/CLOVER/ACPI/Patched" and rename it to ssdt-1.aml. If you have already a ssdt-1, rename it to ssdt-2... Reboot To be sure that your Speed Stepper is patched, download the AppleIntelCPUPowerManagementInfo.kext and add it to your System/Library/Extensions/ folder with the kext installer of your choice. I for one better in Kext Utility. Rebuild cache with the app of your choice (kext utility make that automaticly) and reboot. At start, open your terminal app and type this command : cat /var/log/system.log | grep "AICPUPMI:" If you can see a lot of P-States, you did a good job. About problems Problem with auto ON after sleep Past this method before the M_OF method in your DSDT : Method (M_ON, 0, NotSerialized) { If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._ON)) { \_SB_.PCI0.PEG0.PEGP._ON() } If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._PS0)) { \_SB_.PCI0.PEG0.PEGP._PS0() } If (CondRefOf(\_SB_.PCI0.PEG0.PEGP.SGON)) { \_SB_.PCI0.PEG0.PEGP.SGON() } ​ } After that, call M_ON method in _PTS (Prepare To Sleep) so that the _WAK after sleep can shutdown the card. (thanks to RehabMan) Method (_PTS, 1, NotSerialized) { M_ON () [...] Error of compilation If you find an error of compilation in MacIASL after have make a clean DSDT (with no error), like "Line 1 : Input file does not appear to be an ASL or data table source file" Try to delete all return to the line in the M_ON or M_OF method or just replace it like that : M_OF Method (M_OF, 0, NotSerialized){If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._OFF)){\_SB_.PCI0.PEG0.PEGP._OFF()}If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._PS3)){\_SB_.PCI0.PEG0.PEGP._PS3()}If (CondRefOf(\_SB_.PCI0.PEG0.PEGP.SGOF)){\_SB_.PCI0.PEG0.PEGP.SGOF()}} M_ON Method (M_ON, 0, NotSerialized){If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._ON)){\_SB_.PCI0.PEG0.PEGP._ON()}If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._PS0)){\_SB_.PCI0.PEG0.PEGP._PS0()}If (CondRefOf(\_SB_.PCI0.PEG0.PEGP.SGON)){\_SB_.PCI0.PEG0.PEGP.SGON()}} Credit Thanks to PikeRAlpha for ssdtPRGen.sh Thanks to 'qwerty12' for all informations --> link of her topic Thanks to 'Skvo' for speedster and SSDT solution --> link of her post Thanks to RehabMan for their instructions Thanks to LexHimself for the SSDT method
  2. Ciao ragazzi, qualche giorno fa ho comprato un monitor con un solo output: VGA, non sapendo che il MAC potesse accettare in ingresso solo segnali digitali. Cosa mi consigliate di fare: Comprare un convertitore DVI-D to VGA tipo questo? http://it.startech.com/AV/Convertitori/Video/Cavo-convertitore-adattatore-attivo-DVI-D-a-VGA-1920x1200~DVI2VGAE Posso modificare qualche cosa all'interno dei driver per non spendere soldi? Buttare tutto in aria. P.S. Io uso la scheda grafica integrata del mio i5 4670 Haswell HD 4600 - Ho a disposizione porta VGA - DVI-D - HDMI

    Help me Disabling NVIDIA

    Hey bro, would you like to help me to disable my NVIDIA cars using my own created DSDT I have tried it but it failed while compiling DropTable.zip
  4. Hello , I have a pc ASUS F550ZE - xx072t A10-7400P with AMD processor with AMD Radeon R6 and a dedicated AMD Radeon R7 265DX . You can disable your graphics card using the DSDT file located in bootloader ?
  5. So essentially, after many years I finally got enough new parts to build a new PC with a Quad Core CPU. I previously had a Core 2 Duo w/ a MSI 975x Platinum Power-Up Edition Board that I had successfully installed 10.4, 10.5,10.6, and 10.8. While using another hard drive to run windows. Now I have: ASUS Sabertooth P67 (rev 3.1) Core i5 3570k AMD Radeon HD 6970 I've come to learn that the Radeon HD 6790 is essentially not compatible with any Mac OS, which I can learn to live with. I was at least able to install a distro of Mavericks and boot into safe mode for now. My random thought was this.. I have an older Radeon HD 4670 now laying around without a home. Could I put both in the PC and then just disable the card depending on the OS? IE. Use the newer card in windows 8 or Windows 7 on the one hard drive, and then run Mac OS and have it disable the newer incompatible card? I tried plugging it in for kicks and giggles and was at least still able to boot in safe mode, but I don't see an easy way of disabling the problematic card short of removing it every time i want to use Mac Os which doesn't really sound great long term. Any thoughts or suggestions? I plan on getting rid of the distro and installing as vanilla as possible again If i can find some sort of solution for the graphics card. The only posts I found for disabling a graphics chip were from mac pro owners with the lemon units.
