Sorry for the late reply, had to work a lot last week...

 

 

Sound is working! I don't know why, but it's working now. Perhaps just a restart was needed.

Super nice guide!
 

But I need some help here!

 

It´s so strange: I can reach yosemiteinstaller without ACHI enable in BIOS  (dont see my SSD hdd) . So when ACHI is enable I get stuck at "Waiting for DSMOS" and nothing happens.

My specs:

  • Model: DELL LATITUDE E6420
  • Intel Core i5 (2nd Gen) 2520M / 2.5 GHz
  • Intel HD Graphics 3000
  • Scren: 1600 x 900 px

    128 GB ssd

     

     

    SOLVED ---> I did some own adjustments in Clover:

    Instead of following the guide I chose: 

    • install bootOss in MBR
    • CloverEfi 64bit sata
    • Chose all the 64bit drivers
    • Did not choose one of the 64bit Uefi-drivers

    With these adjustments I reached the Yosemite-installer with AHCI enable.

     

    BIG NOTE: It seems that I needed to reconfig BIOS EVERY TIME(1. load default, 2. change the sata-config to ACH) to be able to reach the installer. If I did'nt that Clover would launch in a low-res-mode and the boot would be stuck at "Waiting for DSMOS.

Yes you´re right! I have A09 hahaha. maybe thats why.. Beside this, i got the system running.. thou it would like some driver-adjustments. So I downloaded the EDP-software and totally reconfigure my kexts-libary, using E6220´s files. When I rebooted, I coun´t login because the trackpad and keyboard didn´t work. Now I´m currently reinstalling yosemite to try again! Never give up! Thank you for your help!
