[Guide] Lenovo Y50 (UHD or 1080p) using Clover UEFI (10.11)

[RehabMan]

Thanks for your suggestion but I'm quite desperate...
I'm not a crack in computing and I was so happy to succeed in installing Mavericks on my PC.
I thought I had follow your guide to the letter but obviously not
The problem is that I'm still wondering where and when I missed something.

Start over.
Follow guide in post #1.

So I started over.
Everything is working fine (WiFi, Power Management, Graphics, etc.) except Audio. No device is detected.
I tried to reboot without cache and rebuild the cache as it is said in "Known problems" section but no luck.
Can you take a look at my attached files, please?

Thanks a lot

Your ioreg shows kernel version 13.4.0. That is Mavericks 10.9.5.
This guide is for El Capitan or Sierra.

For Mavericks, you would need to regenerate AppleHDA_ALC283.kext (delete AppleHDA_ALC283.kext, then 'make').
And you will need to use an older RealtekRTL8111.kext.

It is all pretty obvious from the errors from kernel cache:

Prelink failed for com.insanelymac.RealtekRTL8111; omitting from prelinked kernel.
AppleHDA_ALC283.kext - no compatible dependency found for com.apple.iokit.IOAudioFamily.
AppleHDA_ALC283.kext - no compatible dependency found for com.apple.iokit.IOHDAFamily.
Prelink failed for com.apple.driver.AppleHDA; omitting from prelinked kernel.

Thanks so much for your reply.
As I said, I'm quite ill-at-ease with all these practical works.
How can I regenerate AppleHDA_ALC283.kext ? And where can I find an older version of RealtekRTL8111.kext ?

Thanks a lot

You mean I have to type in Terminal :

make clean AppleHDA_ALC283.kext
make AppleHDA_ALC283.kext

?

Sorry I'm a noob

No.
Delete AppleHDA_ALC283.kext, then re-create it.

rm -rf AppleHDA_ALC283.kext
make

 

[lahoule]

No.
Delete AppleHDA_ALC283.kext, then re-create it.

rm -rf AppleHDA_ALC283.kext
make

Thanks but when I do this, I've got this message in Terminal :

make: *** No targets specified and no makefile found. Stop.

macbook-pro-de-lahoule-1:~ lahoule$

Any idea?

Thanks

Your current working directory is not set properly.
You should be in ~/Projects/y50.git, as per guide...
