Hey, it's been a while since I've worked on anything hackintosh related, so I'm not really sure about any of this, I dumped the ACPI tables in linux and got the ones from clover and used the latest iasl version i could find. (20141107) but i keep getting errors about redefined namespaces etc. Does UEFI / BIOS mode make a difference for the ACPI table structure? I got these in UEFI mode.
My laptop is a Clevo P150EM, gfx card a GTX670M.
 
Would really appreciated it if someone would take a quick look and tell me if it's doable or help me out a bit :)


I had no issue disassembling your files. Here's what I did:
- downloaded your tables.zip
- unzip in place
cd ~/Downloads/tables
cd linux
iasl -da -dl DSDT.dat SSDT*.dat
cd ..
cd clover
iasl -da -dl DSDT.aml SSDT*.aml
Both were successful in creating all *.dsl files without error.

Using iasl here: https://bitbucket.or...cpica/downloads

You must be doing something wrong.

Oh wow, I guess i was just too stupid to find the latest version of iasl and use it :) Thanks a lot.

 

Also i realised i have to replace the iasl binary in MacIASL when using that to compile.

Here's a patched DSDT for Clevo P150EM based laptops with a GTX675M in my case (might work with other nvidia cards i don't know)

I tried to also include the method LexHimself describes, not sure if i did it right, don't have a kill-a-watt or something similar to it.

 

For anyone who might need it :)

P.S.: you need to set ig-platform-id to 0x01660004 for Clover's intel injection to work on this model.

I did as it is with a few modifications to fit my system path but NVIDIA is still not disabled.

Please see my DSDT to check whether I'm doing it right or not. Thank you
