Thread: How to install LION on .. Lenovo z470 ? Help me ..

Thanks!! It worked!!
Now I just need to install VoodooHDA.

It still asks for a bluetooh keyboard, but i guess that is normal I've seen this before.

OK...

Before install VoodooHDA, delete AppleHDA.kext from /System/Library/Extensions....

To get sleep working, you need the DSDT and the steps below...

Delete the kext NullCPUPowerManagement.kext from your system (/E/E or /S/L/E)...

Copy the kext AppleRTC.kext to your desktop and run the command below...

Code:

sudo perl -pi -e 's|\x75\x30\x44\x89\xf8|\xeb\x30\x44\x89\xf8|; s|\x75\x3d\x8b\x75\x08|\xeb\x3d\x8b\x75\x08|' /Users/YOURUSER/Desktop/AppleRTC.kext/Contents/MacOS/AppleRTC

After this, install again the kext using Kext Wizard, run the maintenance routines and reboot...

Go in "System Preferences > Bluetooth > Advanced" and uncheck "Open Bluetooth Setup Assistant at Startup if no Keyboard is Detected"...

OK, I deleted AppleHDA and installed VoodooHDA, no errors but Mic is not working. Do I need to edit VoodooHDA?

Probably yes, take a look at this thread > olarila.com • View topic - VoodooHDA - problemas comuns

It worked, changed iMix to 100.

Thank you.

The only thing that does not work are the volume multimedia keys, If I use Volume UP it keeps going up and does not stop, same thing with volume down.

But I don't use them so it is fine.

You need to use the volume keys that are on the "arrows" keys...

And also brightness....

When I' watching youtube videos I can hear strange noises, sometimes the sound fails.

But When listening to music it is normal. Do you know what can cause this kind of problem?

I tried changing to 44100Hz, another solution is to is to enable sse2 but since I don't have VoodooHDA panel, I don't know how to enable it

Some users have similar issues...

I don`t know exactly what is, but they told that moving the mouse or using a application that make
a bit higher processor activity make the noises go...

But you can try some more adjustments on the kext, here you can find sources and also the VoodooHDA preference pane, that make some adjustments more easy > Voodoohda Driver - Project OS X Forums

Enabling SSE2 fixed the problem.

Thanks

Just a quick update, if anyone wants wireless to work b/g/n 64 bits, found a Kext that works
