Litecoin Mining on Mac OS X – GPU Mining

5 stars based on 51 reviews

My previous article on Litecoin mining I discussed how you can get started mining Litecoinsan alternative to the Bitcoin crypto-currency, using your spare CPU cycles. Whether that trade-off is worth-while is a decision you would need to make. Litecoin is litecoin mining guide mac os as mature as Bitcoin and is just as volatile. Some see it as a doomed clone, others as the next Bitcoin, poised to take off.

Please read my previous article on Bitcoin mining for step-by-step instructions and installation packages for cgminer and bfgminer. The Homebrew formulas I shared in my previous article include the configuration settings necessary to mine both Bitcoins and Litecoins.

If you are compiling the applications yourself, make sure to use the —enable-scrypt parameter when running. Armed with a copy of cgminer or bfgminer with scrypt enabled, you can now start mining Litecoins with your GPU.

Now a fair warning: With Bitcoins you can basically run either miner and just specify your pool. The miner will then tune itself and eventually litecoin mining guide mac os a nice hash-rate.

Note that I am using the -d parameter to specify which GPU to use to simplify these examples. Using bfgminer with the basic command-line parameters yields similar results. So how can we get better performance mining Litecoins on the GPU? The first parameter to focus on is the -I parameter, or the intensity. With Bitcoin this parameter does help, but honestly not a ton. This is not the case with Litecoin mining. On my system, is about the best I can do.

The next parameter to focus on is the -w parameter, which specifies litecoin mining guide mac os worksize in multiples of 64 up to This parameter is what really makes a difference on my OS X rig:. The last parameter I want to litecoin mining guide mac os is —thread-concurrency. If cgminer or bfgminer litecoin mining guide mac os reporting hardware errors the HW number in the output this indicates that you need to make use of the —thread-concurrency parameter. These litecoin mining guide mac os not hardware failures.

You can find guidelines for the value to use here:. Ideal values are or Find your bus width here. The growing landscape of crypto-currency is fascinating from many perspectives. If your interest is piqued and you are running OS X, hopefully you now have the information you need in order to get started mining this new form of currency.

Starting with version 3. Additionally, bfgminer now requires an additional argument in order to enable GPU mining. If you wish to use bfgminer for GPU mining you will need to add the following argument:.

Thanks for the excellent guides on starting mining on a Mac. I have been trying it out over the weekend on a couple of different laptops, one Air and one Pro. Obviously, neither of them are heavy hitters but the experimentation is quite fun. I found MacMiner to be better than doing homebrew installs, surprisingly. It gives a cryptic OpenCL initialization error: Enqueueing kernel onto command queue.

Finally was able to get Cgminer to compile and install litecoin mining guide mac os for Lion. Try a worksize of 64 instead of Also, try removing the lookup-gap. If things are stable then start upping the intensity. Thanks for the reply! If i take the intensity past 12 the computer freezes up: I read to add these lines in the terminal before the scrypt: Hey, I need some help.

Thanks for the article. Where does one get a username and password for the Terminal commands please? Can I use this setup for Feathercoin? How do I indicate it to mine feathercoin and not litecoin. It should work as long as your arguments are valid for Scrypt mining. Litecoin and Feathercoin should work the same.

What sort of problems are you having? I have one problem proceeding with cgminer 3. This had me stumped for a couple of hours today. As can be seen here: When you try to install it you will get a SHA-hash error. This worked for me. This has been a very helpful forum and I feel like I was so close. Can you help me?

Sorry for the double post but I have tried everything. What can I do on my computer to speed it up? Is it the mac versions of the that is slow? Thank you for your help. I use -g 1 —thread-concurrency for mybut that is on Windows.

Note that scrypt mining is notoriously difficult to tune and much more so on a Mac. I have never been able to get the same scrypt numbers on a Mac as I can in Windows. Is it the stock power supply? Getting an Error whenever I try and use bfgminer.

Any thoughts on what could be going wrong? Litecoin mining guide mac os opinions on Asteroid? Am I sacrificing anything by using that app instead of a command line process? I seem to be having problems with scrypt that I hope you can lend your expertise to. If I run cgminer without scrypt enabled it seems to hash along happily if slowly with the following command line: If I try to run it scrypt enabled, using this command line: Building Program clBuildProgram [ Your email address will not be published.

So lets try cgminer with -I 13 to see what that does: This parameter is what really makes a difference on my OS X rig: You can find guidelines for the value to use here: I verified that works well with a and works well with a If you litecoin mining guide mac os to use bfgminer for GPU mining you will need to add the following argument: Leave a Reply Cancel reply Your email address will not be published.

My previous series of articles on crypto-currency covered Bitcoin mining on OS X. This series will focus on mining Litecoins. What is Litecoin you may ask? Litecoin is a fork of the Bitcoin project with three important changes:. While SHA benefits from massive, parallel processing, Scrypt is built to be very memory-intensive. This means that, for the time being, mining Litecoins using your CPU which is no longer profitable with Bitcoin is still possible. With the Litecoin wallet you can actually mine from within the UI.

However, as Litecoin CPU mining is generally done within the wallet application though it can be done at the command-line , I want to make two things clear. First , encrypt your wallet. The same thing goes for your Bitcoin wallet. As stated above, the Litecoin wallet UI is capable of showing and controlling mining. While the Litecoin wallet has built in support for solo mining, pooled mining requires another download see my first article for a brief overview of mining pools.

The download is from a project called cpuminer. This makes it possible to use the pooled miner from within the Litecoin wallet. The Mining tab has been removed from the Lightcoin-QT wallet. Skip down a couple of paragraphs for details on mining from the command-line. Switch to the Mining tab in Litecoin-QT. Change the Type to Pool Mining. Set the Threads value to the number of cores you have double that if you have Hyper-threading.

You can leave the Scantime value. For the Server, Port, Username and Password, enter your mining pool information. Using P2Pool mining pools is fairly popular with Litecoin. You can use p2pool. The Litecoin-QT UI will display the output from minerd and a running total of accepted and rejected shares, as well as average hashes-per-second. While mining from within the app is nice as it gives you running totals, you can just as easily mine from the command-line with the following command:.

The command line gives me a bit more info: Any ideas on what might be going wrong? You could try using Homebrew to install libidn if you do not have it. Had you had MacPorts installed at any point? That post sent me in the right direction — thanks! Turns out I was missing both libidn and openssl. I have one with ltc.

This is so frustrating! You can get Homebrew from http: The easiest way to do this is create symlinks aliases that point to the copies that Homebrew created. These commands in the Terminal create the needed folders and create the symlinks:. Hi Jay, I really appreciate you trying to assist me.

As an example, I copied your link for the terminal to get Homebrew and pasted it into the terminal, hit enter…..

It has so many files within the files. I do know that this is the portion that if one single character or space is incorrect, nothing will work. Again, I really appreciate your trying to assist and I wished I were able to understand what you have laid out better. If you live around The Woodlands, TX.

What I really need is someone to just talk me through it over the phone. Musings from the Chiefio. What to do then? The Mining tab is no longer in the latest Litecoin-QT wallet app. Sorry for the confusion! Hello — Lovely article!! Is there a way to enable the mining option in LiteCoin-QT? I have a question. Do I need to setup somehow litecoin wallet to start mining or not? Do I need to setup server IP etc.

I didnt fint the answer. Where do the mined coins go? In my wallet file? Where is it saved, if I dont mine with Litecoin-QT?

You will join a litecoin mining pool of your choice. On the website for your mining pool, normally located in the account area you will enter your wallet address. After that, create a new worker through your pool then use that with your miner. Any coins you collect while mining in your pool will be automatically added to your wallet provided you entered your wallet address in your account settings on the pools website after some time. Do I need to worry about my MBP overheating? But I have a problem now.

My computer is mac book pro. Now I have set it 8. But I have see someone set it 99!!! So I am confused. Looking forward for your answer. I put the ltc wallet and minerd into a folder in the applications folder in my user section. When I open minerd it says no credentials entered and it wont let me type anything. What do I do? Even if I underclock the card.

I believe I have followed the above instructions to the letter, but when I run the command line instruction I get the following error…. I can confirm that minerd is in the same directory as the Litecoin wallet App.
