You probably need to cd into the build folder.

I have the same problem when using this on Macbook Pro 11,3
Even though Mac is installed as EFI

Assuming you are running Linux, you could have a look at the wiki entry about UEFI from Arch: https://wiki.archlinux.org/index.php/Unified_Extensible_Firmware_Interface. Even if you are not using Arch Linux as your distribution, most of the information should apply to other distributions as well.

My discrete graphics called just died in my 2011 15" MBP and I'm trying to use this tool to go to the Integrated Graphics by default even when its booting. I'm getting this same error I'm not sure whether my Mac is installed in "EFI" its just a normal OS X setup. Any idea?

I assume you are trying to switch between GPUs under OS X.
Simply using the Linux script won't help you there.

You have to checkout the osx folder and follow the instructions here: https://github.com/0xbb/gpu-switch#os-x-usage

Hey all,

I am trying to switch to iGPU in osx:

I ran build.sh and it says:

=== BUILD TARGET gpu-switch OF PROJECT gpu-switch WITH CONFIGURATION Release ===
build successfull: ..

so after this I run /.gpu-switch -i and I get the same response @akhats @8a5 @SnakeO

Fatal: gpu-switch has to be run in EFI mode.

How do switch it to iGPU (please) @0xbb, what am I not doing correctly ?

from gpu-switch.

Could you provide the output of the command file ./gpu-switch.
I think you are still running the Linux script.

from gpu-switch.

OK! I ran ./gpu-switch -i from the build folder and it worked!

Please tell me how I can make it do this every time I log out of osx?

There is install_hooks.sh script plus a hooks folder in the osx folder. Here also my support ends.
