[SOLVED] E6420 and osx sierra


Ami

Recommended Posts

Just noticed the thread.  Just wondering Ami, did you upgrade from a previous version (el capitan or yosemite)   I had the same problem and apparently what happened to me was that on El Capitan I was using a patched AppleHDA.kext and it was installed in  S/L/E but once I upgraded to Sierra for some reason that kext was not updated and as such I didn't have the Vanilla AppleHDA.kext.  So I deleted that file and retook the upgrade again.  This time since there was no AppleHDA it reintalled a fresh vanilla one.  Sound worked perfectly then with Jake Lo's and Herve's reccomendations.  So maybe that is the reason you're having issues.  Not sure though.

Ami's issue has been resolved. First he didn't have the DSDT in place. Second, the dummyHDA was not loading, but after a reboot, repair permission and rebuild cache, sound started working. The DSDT also fixed the battery status and USB issue.

Everything is working from yesterday. Think next step will be replacement of the existing Ssd (intel 535 120GB) to the Crucial MX300 275GB. But I think I could challenge everything by my own in the end (new installation I mean; l've got everything now).

Thanks everyone who took part in thread.

Special thanks to Jake Lo.
