Hello Sir,   
I have a ton of problems  
  
First in step 11 : i don't understand this : 
 
Should mavericks user only install this ?! i am on 10.10.3 also i don't have this option in the latest HVT there's only HD4000 DP / FakePCIID HD4600! 
  
Second problem is in SSDT-7.dsl i can't apply both patch
 
[2.05] Haswell HD4400/HD4600/HD5000 
[2.11] Brightness fix (Haswell)
 
only [2.12] Rename GFX0 to IGPU patch work but when i compile it alone i got the error in the picture >> Unexpected '}' 
 
Third Problem :  i don't have in my DSDT folder SSDT-8.dsl and SSDT-9.dsl why is that ?!
 
​My laptop is Dell inspiron 3537 , i'll appreciate your help ... it's been two days trying to get Full Acceleration 
 
P.S : Sound is working after patching the DSDT.dsl
