Trying to install OpenCl Driver open mac

Hi all, 

I am trying to install the OpenCL driver on my macbook pro, which has an Intel HD 4000 GPU. I searched around for a while, and finally found the Intel INDE development package, which I downloaded and tried to install, but got this error:

Error while executing the startup script. Make sure that you have write permissions to /Users/Shared/Library/Application Support/Intel/Licenses folder.

However, I checked and this folder does not exist. 

Two questions: How do I resolve this error? and is there a simpler way to just get the OpenCL driver?

Thanks!!
