E6430 Intel HD4000 artefacts after installation os x 10.11


Recommended Posts


I just followed JakeLo installation Guide by the letter and after installation of El Capitan i got artefacts on boot screen and after logon.

My E6430:
i5 3320m 2.7 ghz
intel hd4000 1600x900



Need help please to solve the artefacts problem and my TP-LINK TL-WN725N Nano USB Wifi with RTL8188CUS chipset.

Just noticed audio not working....


Can anybody point me to the right direction?

Yes, that's what I linked in the post above.


OK! Thanks :)


A12 -> A03 (partition table error) -> A07 (Boot OK, no aretefacts)


Where is the location of kext/other/LE ?? Can't find it :\

Do you mean inside the EFI folder (USB)?


AppleHDA_IDT.kext?? (like in picture)

Already got the RTL8188CUS working with the RTL all-in-one driver package.


But still no audio, even after following the steps you said JakeLo, copy the kext to /Library/Extensions/, run the permission scripts with sudo -s but still no audio,

Once you've added kexts to /L/E, you must repair permissions and rebuild your cache:

sudo chmod -Rf 755 /L*/E*
sudo chown -Rf 0:0 /L*/E*
sudo touch -f /L*/E*
sudo kextcache -Boot -U / (or: sudo kextcache -system-prelinked-kernel)

If you get error messages, re-type the last 2 commands.
