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?


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

1 Answer 1


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

  • well that sucks, but thanks. Here is proof for what your saying.
