How to mine Bitcoin with your Mac, ZDNet

Here’s how to metselspecie ter on the Bitcoin craze by mining on your Mac. But beware, it’s neither elementary strafgevangenis cheap.

How about Tesla?

Pfft. Leave behind about them. Bitcoin is where it’s at.

Bitcoin is a crypto currency that’s bot exploding ter value since the Chairman of the Federal Reserve, Ben Bernanke said that it “may hold long-term promise” at last week’s U.S. Senate hearing on the Potential Risks, Threats, and Promises of Virtual Currencies (which aired on C-SPAN). Other U.S. regulatory power houses (including the Treasury and Department of Justice) agreed.

It’s not without controversy, however. Bitcoin wasgoed the currency of choice at former Internet drug bazaar Silk Road and remains the currency of choice of crypto locker hackers that hold people’s computers hostage for money. But don’t let that discourage you.

When I very first researched Bitcoin (at the end of 2012) the price of a single Bitcoin wasgoed $13.50. Te May 2013 it wasgoed selling for around $200/BTC. When I ultimately got around to buying some Bitcoin (on November Ten) it had leaped to $460/BTC, and spil I write this on November 26 the price has skyrocketed to $920/BTC. Not too shabby.

But enough on the background of Bitcoin, there’s slew of places to read about that. Let’s get down to business and how to mine Bitcoin using your Mac.

Very first, some bad news. While it’s technically possible to mine for BTC using your Mac’s GPU, it’s not profitable. The hashing difficulty has enhanced to a point where you’ll spend more on electro-stimulation than you’ll get te Bitcoin te comeback. It’s possible that the fresh Mac Voor (with it’s dual AMD FirePro GPUs) might be able to mine for Bitcoin profitably, no one’s benchmarked its hashing spectacle yet.

The good news is that you can purchase purpose-built mining hardware that will mine Bitcoin. While potentially profitable, there are several caveats. ASIC mining hardware is backordered, expensive, power greedy and noisy. I backordered a 5Gh/s and a 25Gh/s ASIC (both pictured above) from ButterFly Labs ter May and just got them this month, a six month backorder. If you’re serious about getting into Bitcoin mining I suggest that you either purchase a BFL miner on eBay, or place a pre-order for one of the rip-snortin’ rapid 300 or 600Gh/s miners that Butterfly Labs will start shipping ter January.

If I toevluchthaven’t frightened you off and you’re still reading, here’s what you need to do to start mining for Bitcoin on your Mac.

Create a Bitcoin wallet at BlockChain.informatie and note your Bitcoin address. You’ll need it te step Two. A wallet is used to store your Bitcoin and you can have spil many wallets spil you want. Recall that security is paramount and losing your credentials is akin to losing your physical wallet, except that no one’s going to terugwedstrijd it to you. Also, if you lose your credentials, your Bitcoin is gone forever, there’s no way to recover your password. There are many options for online and offline wallets and an offline wallets are more secure, but if you’re commencing at zero an online wallet is fine for the time being. (If you project on purchasing Bitcoin with real money, then I recommend that you educate yourself on the risks and store your Bitcoin te an offline wallet that is backed up.)

Join a mining pool, like BitcoinCZ Mining (aka Slush’s pool). Bitcoin pooled mining is a way for numerous users to work together to mine Bitcoin, and to share the benefits fairly. Create and record logins and passwords for spil many workers spil you need. If you purchased ASIC hardware to run on one Mac, one worker is sufficient. If you want use a bunch of computers te your huis or office to mine, then create a worker account for each machine that you project to enlist.

Step Three. Install the mining software

There aren’t a lotsbestemming of Bitcoin mining clients for the Mac and if you awkward with the directive line/Terminal (or would just like a little more terugkoppeling) I recommend a free OS X mining client called MacMiner. Download it, install it and configure it to send prizes to your BlockChain wallet and to work ter the pool that you joined. Here’s how.

Step Four. Connect your ASIC miner to your Mac’s USB port.

Step Five. Configure Mac Miner’s Pool Settings

  • Open the FPGA/ASIC Miner window (from the View spijskaart).
  • Click on “Pool Settings” te the upper-left of the FPGA/ASIC Miner window.
  • Inject your BTC address for prizes (from your wallet ter Step 1)
  • Ter the BTC area (bottom left) select your mining pool from the druppel down spijskaart
  • Inject your miner username and password from your mining pool (Step Two above)
  • Click “Save &, commence”

Step 6. Configure Mac Miner’s Miner Settings

  1. Click on “Miner Settings” te the FPGA/ASIC Miner window
  2. Inject “-S all” (without the quotes, capital “P”) te the Devices/manual flags field
  3. Click Apply

Ter the FPGA/ASIC Miner window (ter Step Five above).

Step 8. Observe the Bitcoin roll te

To monitor your progress, loom into your mining pool account and observe the “My Account” pagina. I have Slush’s Pool set to transfer my BTC prizes to my wallet every 0.1 BTC (the “Send threshold” below) and spil you can see by the screenshots, I’ve bot getting 35-36Gh/s hashing spectacle from my two BFL miners pictured above. At 36Gh/s I’ve bot able to mine 0.1 BTC every four days and I’m on a rhythm to mine 1BTC/40 days at the current difficulty level.

The next generation of mining hardware from Butterfly Labs are a pair of PCI cards based packed with 28nm ASICs that are capable of mining at 300Gh/s ($Two,800) and 600Gh/s ($Four,680) respectively. Orders places today for the fresh “Monarch” cards are expected to start shipping te February 2014. KnCMiner, based te of Stockholm Sweden, is taking pre-orders for a Three Terahash miner called Neptune, only 1200 units are being made and one will set you back $12,995. According to the founders, Neptune can mine Two.1 Bitcoin vanaf day at current difficulty levels.

Update 2013-1203: I’ve switched from using MacMiner to Asteroid, a fresh Bitcoin mining client for Mac. More on Asteroid te a future blog postbode.

Q: Can I set up MacMiner on a bunch of computers and mine BTC that way? (ala [email protected])

A: While you can, it’s not economically feasible with the current level of hashing difficulty and the cost of electrical play.

Q: Where can I buy Bitcoin?

A: If you’re ter the U.S., you can buy BTC at Coinbase.com. They’re US-based and raised $5M te venture capital te May 2013 (WSJ article)

Q: Where can I purchase ASIC mining hardware?

A: I purchased two minging equipments (pictured above) from Butterfly Labs and they rock — to the tune of 36Gh. Note: BFL is running a Black Friday Special with 25 procent off mining hardware Friday only (te your local time zone). Minr.informatie maintains a list of presently discussed ASIC bitcoin mining hardware.
