Hi,

I successfully installed OSX Yosemite with the help of:
How To Install OS X Yosemite Using Clover

Then I followed the Lenovo T440s guide:
[Guide] Lenovo T440s Clover UEFI

Now I have the following problems:

  • I couldn't get the ALC292 to work, don't have a patched kext for it(went with VoodooHDA_X1Carbon for the mic and sound to work)
  • I get a screen garble only at the login screen (I am aware that this was an 10.10.2 and 10.10.3 issue) BUT accelerated programs like Blender/Maya also produce artifacts!! I read that it could or is a opengl problem and found [Fix] Intel HD4200/HD4400/HD4600 Mobile on Yosemite
  • I still have a problem with usb failing after wakeup what fix could I use?
  • The lenovo t440s guide had the following add-ons:
FakePCIID.kext
FakePCIID_HD4600_HD4400.kext
FakePCIID_Intel_HDMI_Audio.kext
FakeSMC.kext

Question: Can I just place the needed kext addons in:
/EFI/Clover/kexts/Other and be done? or do I need (force load kext) to patch it in order to work?

When I downloaded the FakePCIID fix for HD4600 according to this guide:
[Fix] Intel HD4200/HD4400/HD4600 Mobile on Yosemite

my laptop refused to boot after applying the suggested kext. Question: Is it necessary to install all the FakePCIID kexts as found in the Lenovo T440s Guide in order for this to even work?

If someone could help me sort these problems out, that would be great, thanks

Hi,

[Guide] Lenovo T440s Clover UEFI
I think your links are reversed.

Using a desktop guide on laptop, not recommended. Laptop guide: http://www.tonymacx86.com/yosemite-laptop-support/148093-guide-booting-os-x-installer-laptops-clover-uefi.html

Now I have the following problems:

[*]I couldn't get the ALC292 to work, don't have a patched kext for it(went with VoodooHDA_X1Carbon for the mic and sound to work)
Audio: Best result with patched AppleHDA. Google 'patch AppleHDA guide'. Search for suitable AppleHDA or patch it yourself. Apply appropriate DSDT patches.

DSDT patches for patched AppleHDA are covered in the DSDT/SSDT patching guide: http://www.tonymacx86.com/yosemite-laptop-support/152573-guide-patching-laptop-dsdt-ssdts.html

[*]I get a screen garble only at the login screen (I am aware that this was an 10.10.2 and 10.10.3 issue) BUT accelerated programs like Blender/Maya also produce artifacts!! I read that it could or is a opengl problem and found [Fix] Intel HD4200/HD4400/HD4600 Mobile on Yosemite

If you had followed the laptop Clover guide, you probably would not be having the issue...

[*]I still have a problem with usb failing after wakeup what fix could I use?

FakePCIID_HD4600_HD4400.kext
FakePCIID_Intel_HDMI_Audio.kext
FakeSMC.kext

All kexts should be installed to /S/L/E using a kext installer (such as Kext Wizard).

When I downloaded the FakePCIID fix for HD4600 according to this guide:
[Fix] Intel HD4200/HD4400/HD4600 Mobile on Yosemite

FakeSMC is required. You should boot verbose for troubleshooting.
