Does cgminer work with Mac GPU?

[loourr]

I succesfully installed cgminer on my mac but every time I try to run it I get the message

[2013-09-16 15:03:49] clDevicesNum returned error, no GPUs usable

why is this? Is it that you cannot mine with the GPU on a mac, or am I just doing something wrong?

Specs:

Macbook Pro (2011)
Mac OS X Lion 10.7.5
Intel HD Graphics 3000 384 MB

I'm pretty sure the reason is that the graphics card does not support openCL
