  1. Hi all I got an ASUS U41SV with a discrete NVIDIA graphics card, and I have reached a solution to disable it in OS X. Spec of the laptop CPU: Intel Core i5-2410M 2.3 GHz Memory: 8GB DDR3 1333 MHz Chipset: Intel HM65 Graphics: Intel HD3000 + NVIDIA GeForce GT540M Display: 14" 1366 x 768 Audio codec: Realtek ALC269 WiFi: Atheros 9285 OS X Configuration Niresh's distro of Yosemite A whole SSD reserved for OS X Chameleon bootloader SMBIOS: MacBookPro8,1 (13-inch, Early 2011) Updated to 10.10.1 via App Store Disabling Optimus The guide here does not fit this laptop, but after some modifications, it works on U41SV. I first extracted DSDT under Windows with AIDA64 Back to OS X, I used MaciASL to edit the DSDT extracted from Windows At the begging of the file, I added the following line: // ... DefinitionBlock ("iASLnv4Cgf.aml", "DSDT", 1, "_ASUS_", "Notebook", 0x00000000) { // the line below was added External (\_SB_.PCI0.PEG0.GFX0.SGOF, MethodObj) // ... Then I added the following method before Method (_WAK, 1, Serialized) // ... Method (M_OF, 0, NotSerialized) { If (CondRefOf (\_SB.PCI0.PEG0.GFX0._OFF)) { \_SB.PCI0.PEG0.GFX0._OFF () } If (CondRefOf (\_SB.PCI0.PEG0.GFX0._PS3)) { \_SB.PCI0.PEG0.GFX0._PS3 () } If (CondRefOf (\_SB.PCI0.PEG0.GFX0.SGOF)) { \_SB.PCI0.PEG0.GFX0.SGOF () } } // ... Then called the method M_OF in the method _WAK // ... Method (_WAK, 1, Serialized) { M_OF () // calling M_OF () WAK (Arg0) Return (Package (0x02) { Zero, Zero }) } // ... And called the method M_OF again in the method _INI // ... Scope (_SB.PCI0) { Method (_INI, 0, NotSerialized) { Store (0x07D0, OSYS) M_OF () // calling M_OF () If (CondRefOf (\_OSI, Local0)) { If (_OSI ("Linux")) { Store (0x03E8, OSYS) } // ... Finally clicked compile in MaciASL, and saved the DSDT as /Extra/DSDT.aml And now NVIDIA Optimus is disabled. Edit: HDMI output working, VGA untested, able to adjust brightness of built-in display And here is my edited DSDT. ASUS-U41SV-DSDT.aml.zip Credits Thanks to Whit3Spirit for the guide here
