I am trying to run a bitcoin miner (bfgminer), I know this is not efficient but I want to do it anyway.

The mac in question is a MacMimi running an Intel HD Graphics 4000 GPU and Intel(R) Core(TM) i7-3615QM CPU @ 2.30GHz. The os Mac OSX 10.8.5.

I have outlined my problem on the bitcoin stackexchange site. I also did a google search and duckduck search with various combinations of the terms "Where is the specific driver for my GPU osx".

I am trying to hard specify the GPU driver for gpfminer when it starts as it is not detecting the GPU.

What is the location of this driver on OSX?

bfgminer specifies that is should be in the form of erupter:/dev/cu.SLAB_USBtoUART

  • Where does bfgminer give that path - and is that for OSX or is that a Linux path?

  • It is an OS X path.

On OSX the drivers are in /System/Library/Extensions

You'll find 3 files starting with AppleIntelHD4000Graphics.

  • Thanks, they are directories. I just tried AppleIntelHD4000GraphicsGLDriver.bundle/ AppleIntelHD4000GraphicsVADriver.bundle/ and neither works,... any other thoughts?

  • What about the kext (kernel extensions) ? Dec 5 '13 at 2:12
  • No, go. When I specify /System/Library/Extensions/AppleIntelHD4000Graphics.kext/Contents/MacOS/AppleIntelHD4000Graphics as the driver.
