I already did in the config attached above. Have you tested it? Can't see image clearly, too small.

We'll need more information. What's the model, include CPU, GPU, display resolution... What boot loader are you using? Chameleon, Clover? Which OS X version? What process were you following?

You need to set the DVMT pre-allocated memory in BIOS settings to 96MB. If your BIOS is locked, then you'll need to patch the FB to pass the Stolen Memory assertion. It's already in your Config file, it just needs to be enabled. I set InjectIntel = True and ig-platform-id=0x16260006 and enable the FB patch. Hope this helps. config.plist.zip

From a quick look, the patched looks ok. But I went ahead and patched your original. Place it in /Extra/Extensions. Launch myHack/myfix (quick). HD4600_HDMI.zip

Try this and install FakePCIID_BCM94352Z_as_BCM94360CS2.kext to /S/L/E

See post #19 of his guide to manually patch it. Or if you are planning to upgrade to 10.10.x, he included the patched files in his bootpacks. Let us know if you need assistance patching it.

If you have Optimus disabled, then use Wern's DSDT. If you have it enabled, then it depends on your display resolution. Select one of these and rename to DSDT.aml E6420/E6520 Optimus Enabled = DSDT-off.aml ; Check Optimus in BIOS, low Res 1366x768 and below E6420/E6520 Optimus Enabled = DSDT-off_2ch.aml ; Check Optimus in BIOS, higher Res 1600x900 and higher

DSDT was already patched for SD Card reader. Check Disk Utility to see if it needs to be formatted. Please upload your latest ioreg so it could be confirmed.

Add NullCPUPowermanagement.kext to /Extra/Extensions or install the patched AICPUPM from Hervé's link to /System/Library/Extensions

boot with -v -f and then post the error screen

run in terminal sudo touch /S*/L*/E* && sudo kextcache -Boot -U / What's the resolution of your display? Make sure to select the correct DSDT base on that.

* Wern has a DSDT for Nvs4200M that has sleep/wake working. See here.

Are you installing with Optimus Enable or Disable? Make sure to use the correct DSDT depending on what you select. If you do have NVS4200m, I think it'll be best to disable Optimus and use Wern's DSDT since he was able to get sleep to work with it. Update: * Wern has a DSDT for Nvs4200M that has sleep/wake working. See here. Make sure to set the BIOS accordingly. Best result is to set BIOS to 'Load Default', hit apply, and then got to SATA Operations and set it to AHCI. Oh and under video, make sure Optimus is uncheck.

R4RC1 version test V3 id E7=0x73 0x02 0x64, EC=0x88 0x07 0x9d (E6x20 models) Didn't test since Wern and Gia were already testing V3 id E7=0x73 0x03 0x0a, EC=0x88 0x08 0x1d (E6430/E6230/Exx30) - KP on both Yosemite and Mavericks - I tested several times just to confirm I didn't do something wrong - Hope you could figure this out since the older version works but only on Yosemite and newer (R3RC4) V3 id E7=0x73 0x03 0x0a, EC=0x88 0x08 0x22 (E7440/E7240/Precision M6800) Tested on Mavericks, Yosemite and El Capitan beta. - Trackstick works well with scrolling / set speed to 3/4 - Right click with 2 finger tab - works fine - Tab and drag works fine - Touchpad scrolling works best with Middle and Ring fingers or middle finger on top of index finger - Touchpad works with inertia - works quite well, no pointer jumping - Side scrolling - no inertia, works as before

try removing OsxAptioFix2Drv-64.efi from drivers64UEFI

@girardpallet which recommendation are you referring to? Refer back to the last few posts. No issue for uranis. His Memory shows correctly as are mine. @uranis, No ,sdcard reader needs to be patch to work, not OOB.

Keyboard backlight Fn+right arrow if you have that function. It should have the icon on it. Thanks for the confirmation. Does the new DSDT fix the HDMI hot plugging issue? Sleep with LID Close? Wake with LID Open?

See if this DSDT makes a difference. Rename it to DSDT.aml Can you confirm the following are working? Internal speaker / headphone Sleep / wake volume control (which key combo?) brightness control ( which key combo?) keyboard back if included (which key combo?) SD Card reader touchpad / trackstick scrolling DSDT-HDMI.aml.zip

At the Chameleon boot screen, enter -v -f to determine what's causing the hang

Remove that and use mine included in this package here

It wasn't done correctly. See the differences attached. I also added some extra config and patch your DSDT to enable HDMI audio, and SD Card reader. Install this to /S/L/E to fix audio after wake issue. Remove GenericUSBXHCI if you have it installed. Not needed. uranis_DSDT+Config.zip

add this to Clover Config under KextToPatch for remedy the menu bar glitch. The Vram change is just cosmetics and of no concern. <dict> <key>Comment</key> <string>0x0a260006 9MB cursor bytes patch</string> <key>Find</key> <data> BgAmCgEDAwMAAAACAAAwAQAAYAA= </data> <key>Name</key> <string>AppleIntelFramebufferAzul</string> <key>Replace</key> <data> BgAmCgEDAwMAAAACAAAwAQAAkAA= </data> </dict>

That's how it works, the sound going through the tv and you control the volume from there. Hot plugging should work too. Make sure to select the HDMI sound output after you plug in the HDMI TV. You could update your 1st post with the installation guide. Updating won't be an issue, you just need to repatch the kexts with the perl patches. You could use my updated kext from my E7440 guide under Updates 10.10.5. You could keep your DSDT and SSDT. Read through my guide carefully. You need the patched Kernel and Nullcpupowermanagement before you do the update and reboot, otherwise KP.

Ok, you have the unsupported ID 8086:0c0c. You'll need to install this FakeID to inject the supported id 8086:0a0c. Download this and install FakePCIID_Intel_HDMI_Audio.kext to /S/L/E

You have to compress files to be able to attach them. Good, a little search in the forum goes a long way. I might have to update Pokenguyen's guide with the latest development of this model, so it'll be less questions like this. I hope he doesn't mind since he has not been active here for a while.
