Snap Coin MacOS CPU Miner

High-performance Snapcoin CPU miner for macOS, optimized for RandomX and designed to run under Rosetta (x86_64) on Apple Silicon for maximum hashrate and stability.

Features

• Full MacOS compatibility (Apple Silicon and Intel Mac)
• High Performance
• Fully Open-Source, built by miner for miners.

Requirements

macOS version: 11.0 (Big Sur)

Rosetta (Only for Apple Silicon Macs):

softwareupdate --install-rosetta

Rust (It can be installed by running this command):

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Node Preparation (Skip this step if on Intel Mac)

Important ⚠️

Snap Coin Node currently only works on Linux and Windows device, so you will need an pc for this to work. How to install an Node is described in this github repository:

https://github.com/snap-coin/snap-coin-node

Snap Coin needs an local node that is connected to the network for the miner to work. Unfortunately the node won't work on Macs, so we will need to do an port tunneling to windows or linux pc. This way the miner will see the port on the wifi not only localhost (User needs to be on the same network, otherwise it won't work)

Step 1 Windows: Install and enable OpenSSH Server

Install an OpenSSH Server

On Windows 10/11:

Open settings with:

Win + I

Then search:

Optional Features

and click on:

View Features

then on:

See Available Features

and there search for:

OpenSSH Server

and click install.

When the install is compleated open powershell as administrator and type:

Start-Service sshd
Set-Service -Name sshd -StartupType Automatic

check if it is running by:

Get-Service sshd

Step 2 Windows: Allow SSH through the firewall

Next you will need to allow SSH through the firewall Powershell as Admin:

New-NetFirewallRule -Name "OpenSSH-Server-In-TCP" -DisplayName "OpenSSH Server (sshd)" -Enabled True -Direction Inbound -Protocol TCP -Action Allow -LocalPort 22

Step 3 Windows: Confirm you can log in via SSH

Now in cmd type this:

ipconfig

You will need to find something like this:

IPv4 Address . . . : 192.168.0.0

Write down the whole IPv4 adress, it will be needed later.

Also in cmd type this:

whoami

Example result:

DESKTOP-XXXX\<username>

Write down the username after the backslash , it will be needed later.

Step 4 Windows: Run the Snapcoin node

Now confirm the API is listenning locally (on Windows in powershell):

netstat -ano | findstr :3003

You should see it listening on 127.0.0.1:3003 or 0.0.0.0:3003. If it listens ONLY on 127.0.0.1:3003, tunneling is perfect.

Step 5 Mac: Verify you can SSH into Windows

First in terminal try connecting with the windows pc: (change the WINDOWS_USER and WINDOWS_IP with your username and ip)

ssh WINDOWS_USER@WINDOWS_IP

If you get a host key warning (changed), fix it:

ssh-keygen -R WINDOWS_IP

If everything works, go to the next step, if not check if you done everything step by step.

Step 6 Mac: Create the SSH tunnel (very important ⚠️)

On Mac in terminal paste this :

ssh -L 4003:127.0.0.1:3003 WINDOWS_USER@WINDOWS_IP

After running this you will need to keep the terminal opened at all times you want to mine. What it does:

• Local Mac port 4003
• Forwards to Windows localhost port 3003

Step 7 Mac: Confirm the tunnel works

Open a new terminal on Mac and run:

nc -vz 127.0.0.1 4003

If it says succeeded, congratulations tunnel works and you are ready to mine!

Node API you should use is:

"api": "127.0.0.1:4003"

Instalation

Download via Cargo

Download via cargo by using this command:

cargo install snapcoin-cpu-miner-macos

Download via Github (Manually)

First download the latest release on Github (It will be an zip file) or by running:

 curl -L \
  -o snapcoin-cpu-miner-macos.zip \   
  https://github.com/MansyonDev/snapcoin-cpuminer-macos/releases/latest/download/snapcoin-cpu-miner-macos.zip

Then extract it:

unzip snapcoin-cpu-miner-macos.zip

Make a folder (ex. snapcoin) and move the miner to the folder

mkdir snapcoin

mv snapcoin-cpu-miner-macos /snapcoin

And the installation is compleated.

Running the miner

Via Cargo (Intel and Apple Silicon)

After installing the miner, you can run it by running

snapcoin-cpu-miner-macos

You will be prompted with an error that says

config.json was not found.
A default config.json has been created.
Please edit it and put your SnapCoin wallet address inside.

An config.json file will be made where you will need to put an Snap Coin wallet address.

How to install an Snap Coin wallet is described in this github repository: (Wallet currently works only on Linux and Windows, so you will need an pc for this to work)

https://github.com/snap-coin/snap-coin-wallet

After getting an public key, enter it in the config.json in the "miner" space. (Double check if you entered the wallet key correctly otherwise you will not earn any SNAP)

Via Github (Manually)

Intel Macs

On Intel Macs in order to run the miner run this command:

./snapcoin-cpu-miner-macos

You will be prompted with an error that says

config.json was not found.
A default config.json has been created.
Please edit it and put your SnapCoin wallet address inside.

An config.json file will be made where you will need to put an Snap Coin wallet address. and also you will need to change the API port from 4003 to 3003 for the miner to correctly see the node. ("api": "127.0.0.1:3003") Only if you ran the node on the same laptop. Otherwise don't change it if running through windows.

Apple Silicon Macs

On Apple Silicon Macs in order to run the miner you will need to have Rosetta installed on your system (Install by pasting this into terminal):

softwareupdate --install-rosetta

After the install run the miner by running this command:

arch -x86_64 ./snapcoin-cpu-miner-macos

You will be prompted with an error that says

config.json was not found.
A default config.json has been created.
Please edit it and put your SnapCoin wallet address inside.

An config.json file will be made where you will need to put an Snap Coin wallet address. Also make sure the API is pointing at ("api": "127.0.0.1:4003") and the node port tunneling is running, if not check the NODE PREPARATION to prepare.

Dev Fee

I implemeted an 1% dev fee from each block mined using this software, it really supports the development and keeps the motivation up. The fee is calculated by 1 block goes to developer (me ;) per 100 blocks mined by the miner so 99 blocks stay with the miner If you don't agree with the 1% dev fee, feel free to just go down to 0%.
