Let's get started...

I use the myhack method for this build, so follow instructions to build your USB installer, set BIOS settings and run the OSX Installation from http://myhack.sojugarden.com/guide/

 

:excl: For best results, set BIOS to default, apply it and then  go back to set Sata Operation to AHCI
 
  1. After creating your USB installer, run myHack again

  2. Select Install Extra and point to the Extra folder attached (extract it first)   Extra_Mav.zip
  3. Boot up system with USB installer disk with flag -v -f (hit F12 - for boot options)

  4. Select your language and hit continue

  5. Click on Utilities and select Disk Utility

  6. Format the HDD per instruction from myHack site (GPT and Journaled preferably)

  7. Close Utilities and hit Continue to start the Installation

  8. Select "Use my Own" when prompt, point it to the Extra folder in the root of the USB installer drive

  9. When prompt to remove problematic kexts, select Yes, Yes, No

  10. System will automatically reboot when finish. Remove the USB installer drive

  11. You'll encounter "Invalid Partition Table" during boot, just hit the Enter key to continue

  12. Boot with -v flag to complete the installation

  13. After logging on: in System Preferences
  •    Enable Clicking for Trackpad

  •    Allow apps downloaded from: Anywhere for Security &Privacy

   14. Launch myHack, Install Chameleon to fix the "Invalid Partition Table" error

   15. Install AppleHDA in /Extra/Extensions/SLE to /S/L/E with kextwizard, run myfix once more 

 

:excl: For Models with i7-4600u and 1920x1080 resolution

  • Replace SSDT SSDT.aml.zip
  • Change Graphics Mode to 1920x1080x32

Ok, that's what I thought. The MBA6,x profile seems to give only LFM and HFM + all turbo boost frequencies, whereas the MBP11,1 gives an extra intermediary step. So it's an i7-4600u@2.1GHz your have then, not an i5-4300u. Over time, you should see boost frequencies in the range 22 to 29/33 (depending on number of active cores).
