user4241: 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


user3310: That generation of Intel integrated graphics does not have OpenCL support, which is needed for mining.
