Bitcoin Mining on Mac OS X – HashBuster ASICs

Another new ASIC is hitting the streets based on the same 55nm Bitfury ASIC chip found in the Blue & Red Fury USB sticks. This new board, known as the HashBuster Micro, packs nine of the chips found on the Bitfury USB sticks, clocking in at around 23 Gh/s once it is setup and hashing. And, like the previous ASICs I’ve looked at, with a small amount of work is is a wonderful Bitcoin hasher under Mac OS X.


Hardware Purchase

The HashBuster Micro board is available from for 1 BTC, but is currently sold out. You can also purchase them from the Eligius mining pool store. They are 0.86 BTC and ship very quickly (I had mine in four days).

Hardware Preparation

Now this may either be a turn off or a draw for you, but either way: the HashBuster Micro does require a small amount of hardware DIY before it will be ready to mine. What comes in the box is the PCB board, a barrel plug for power (with bare wires at the end), and a USB cable. There is no fan, no heat-sinks, and you will need to work out how to get power to the board. Here is the board as it comes in the box:


So you’ll want to purchase at least one 80mm fan, either a single CPU heat sink or a pack of mosfet head sinks, and a 12 volt, 5 amp power brick (if you do not have one). Here’s a quick order list from Amazon:

Miner Installation

Unlike the ASICMINER Block Erupters and Red/Blue Fury USB sticks, the HashBuster Micro is currently only supported by bfgminer. So, the first step is to install bfgminer on OS X. There are several ways to go about this, from compiling bfgminer yourself, to using Homebrew, to downloading a precompiled binary.

There is a thread here on the Bitcoin Talk forums which discusses various ways to install bfgminer on Mac OS X. One of the more full-proof methods is to use Homebrew:

  1. Launch from Spotlight or from your Applications folder
  2. Install Homebrew by entering the following command:
    ruby -e "$(curl -fsSL"
  3. Run the following command and fix any reported issues:
    brew doctor
  4. Tap this Homebrew repostory so that you can install packages from it:
    brew tap nwoolls/xgminer
  5. Finally, install either cgminer or bfgminer:
    brew install bfgminer

If you’d like to install the miner using the latest source from Github rather than the latest official package, use the –HEAD (two dashes prefix) parameter, e.g.:

brew install bfgminer --HEAD

Driver Installation

Unlike the ASICMiner Block Erupters and Bitfury USB sticks, the HashBuster Micro requires no installed kernel extension or driver. Woo-hoo!


Once you have the proper Bitcoin mining software installed, you can use the -d? argument to list available devices with bfgminer:

bfgminer -d?
[2013-12-10 10:07:35] Started bfgminer 3.8.1
[2013-12-10 10:07:38] Devices detected:
[2013-12-10 10:07:38] HashBuster.micro Project by HashBuster for (driver=hashbusterusb; procs=9; serial=180000005298AB36; path=usb:093:002)
1 devices listed


Once the HashBuster Micro is detected you can fire up bfminer using the -o, -u and -p arguments to start hashing away:

bfgminer -o hostname -u username -p password


Feel free to leave any questions below or on this thread on the Bitcoin Talk forums. As always, happy mining!
