Hi RehabMan and mastermilad,

I would like to know if you have fixed your different problems.
I also have a Dell inspiron 7520, and my OS X is running on dual-boot.
I also have a problem with the multibeast configuration (DSDT). I've tried different settings but i cannot have any sounds. When I'm trying other settings my keyboard doesn't run anymore so I have to reinstall all OS X..
Do you have any DSDT file who works with the Dell inspiron 15r 7520?
Thanks for your reply, and have a nice day!
 
Hi.
I have the same laptop.
Did you get success with the video card?

Thanks!
Good Luck.

HD4000 should not be a problem...

System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
System: HP ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx). For a laptop, these details are important and affect critical installation procedures.
