i've found the problem,  when i run the last line in terminal, show this:"Untrusted kext ar not allowed. dummyalc270. kext has invalid signature.  omitting" 

Im searching to resolve this

Now i have the dummy load but i have no sound yet

I see in "about mac"  all input and output but not in preferences of system

Finally i got sound,  only thing i wonder if you kown Jake is how can i get external output,  i see the option on "information of system"  but when i plug in nothing happens 

yes i did, i installed the same is working in Yosemite

 

add this additional patch to your config for audio under kextToPatch

I haven't sound neither 

I have all working but sound and HDMI

What kext?

did you try install with -x ? do you have a external monitor ? maybe there is the solution for mine i cant install with external i have to remove and install it with laptop monitor

Can you install it? or even doesn't install?

Install it and then tell me if doesnt work, at the installation doesnt work all

Did you installed or only boot from usb installation?

Do you have the same laptop? if you haven't then you have to use other files to you computer

The last update include the new trackpad kext, about the sleep i dont know i never use it

How may hours of battery you can get? Mine is like 2 hours at it maximum, 1:50 average.

I get the same more or less, 1:30 of average  

And there is no fix for that? It's always like that?

I don´t know if we can fix it but i don´t think so and for mine work fine and neither i get high temperatures

Wow, thought i was the only one, and... In windows, what are your temps? 

 

Because mine are like 36-45.

Yes, windows use more the low frequency, in my mac always is over 2ghz. Thats one of reasons of the battery duration. 

Is the same processor man, intel i7 3610qm, the only difference from you laptop and mine is the Nvidia card, mine is 610m, yours is 630m, and i'm using my own dsdt and SSDT, but my pc is over 56º always.

Mine is the same arround these temperature 

PD. OP Updated with kext to patch alc270 with clover, no more Applehda

use your own dsdt and ssdt maybe your processor is different

i don't use hdmi for audio for ,i every thing use audio jack 3.5

i think do you need parching AppleIntelFramebufferCapri.kext for audio

Yes i know but the old version doesnt work. I tried to patch it but nothing happen

I solved, i'll upload the zip

Hi there. I have X401A with Core i3 and now I have everything work except headphones output. the audio codec is alc272 but it work with alc270 too. My question is : How can I get headphones output work? Because no headphones option in Sound prefer~.
