If you're following his guide, then download HVT from there. Then install macIASL and IASL with that tool.

Here's the patched file by joe82 for the E7440. Can't guarantee if it'll work for yours or not. Remove the patched string above, AppleHDAALC, and install this to SLE. Layoutid=1 in DSDT. AppleHDA_1010.zip

With Optimus enabled, non of the external display will work. If you want to use HDMI video, you'll have to display Optimus and use the Nvidia card. But of course with this, you'll lose sleep capability.

Try this by Mirone. Layoutid = 3

You might have to use the Intel HD 4400 graphics.

Have you tried 2.8.6 or 2.8.7?

Thanks peekstar. Here's the updated patch for 10.9.5 and 10.10 AppleHDA-2.6.3f4-92HD93bxx_Peekstar.zip AppleHDA-266.5-92HD93bxx_Peekstar.zip

Are you sure you got the CPU right? Unless you mean NVIDIA GeForce GT 720M 2GB Then what's your CPU? For Clover, you can try this guide. It's pretty detailed.

Here, the file is patched. Go ahead and remove the above code. Install it to SLE and backup the original just in case. AppleIntelFramebufferAzul.kext.zip

New guide here by Herve.

Follow installation documentation here. Preinstallation Installation Post Installation. Read thoroughly before you get started. Use the boot pack from this guide. Very similar to your model.

Upload the 2.3.0 version and I'll see if I could upgrade it to Yosemite to test. Thanks.

You have a better working AppleHDA before?

Use ACPIBatteryManager v1.5.3. Patch AICPM and remove NullCPM. You can use your DSDT and SSDT from your Mavericks installation. If you want me to try patch your DSDT, extract it with MacIASL and send it. Can't help with the AppleHDA mic, I didn't create the patch, I just update it to latest version. I was originally patched by our developer EmlyDenish and then modded by ktbos.

You need the vanilla AppleHDA in SLE, remove Voodoohda and AppleHDADisabler. Add kext-dev-mode=1 to boot

Folks, to get SD Card reader working without killing sleep, try this Credit goes to joe82. The VEN/DEV will not be the same. For my E6420/E6430/6430U, it's pci1217,8221 You could skip the DSDT edits, it'll work fine without it. Enjoy!

Welcome Dragonfire. Enjoy your stay.

Yes, that will fix the issue. Add the above code under KextsToPatch in the config.plist.

Enable kext-dev-mode=1

Add nullCPUPowerManagement to 1010. After that you could patch the AppleIntelCPUPowerManagement and remove nullCPU...

The ALC3226 is ALC292 when you extract it from linux dump. Although your ven/dev might be different. Mine is 80809c20, yours might be 80868c20. Try and see if this works.

AppleHDAALC.kext.zip

Are you using the HD4000 or Nvs5200m?

What's your sound card? VGA is no longer supported.

Congratulations! Enjoy!
