[Solved] Brightness Issues - ThinkPad X201 macOS 10.12.6

[lucasdessy]

Recently I've installed macOS 10.12.6 (Sierra) on my ThinkPad X201, and I could get everything working, except for the brightness.

 

I can't make it work, I've applied a bunch of patches on DSDT and couldn't get working, so I decided to apply these patches in SSDT and... I couldn't get working as well.

 

After a while doing some search I realize that for macOS 10.12.4 and above, the patches that I was applying doesn't work, and I would have to use the AppleBacklightInjector kext patch.

 

I've tried the kext patch and doesn't work too. Am I doing something wrong? or my system doesn't support MacOS brightness control at all?

At clover boot screen press F4 to dump origin files and then attach output of https://osxlatitude.com/index.php?/topic/10209-how-to-generate-proper-problem-reporting-files

Thanks for the reply, but I've succesfully downgraded to 10.12.2 and I've got everything working, I'll post my files for who needs a thinkpad fully working in 10.12.x 
 
Everything is working, also sleep is working.

Do you have CPU power management/SpeedStep properly working for your i5-560M?

 

I ask because:

• your files include a CPU power management SSDT table generated by Pike R Alpha's tool
• your Clover config does not generate P-States/C-States
• your Clover config has AICPUPM patch enabled

i.e. you use the CPU power management setup usually applicable to SandyBridge/IvyBridge, not to Arrandale.

yes, it works, but looks like turbo boost is not working..

Try without the generated SSDT, without the AICPUPM patch and with P States + C states generation.
