This is the revised version of my previous post how to mine eth with gpu on your mac. It showed less performance than the devices can do and only worked with minergate pool.

I've tried compiling from source code and got better result than my previous one. I'm not sure all problems are solved, but it definitely shows improved result.

Let's do it.

1. Prerequisites

XCode

I'm not sure whether it must be needed or not, but I think you have to install it to build from source code.
Ethereum wallet address

I've tested with ethermine pool and dwarfpool with my own eth wallet address.

Now, open Terminal app and run the following commands.

2. Install CMake

You can skip this step if you already installed CMake on your system

2.1 Install Homebrew

You can skip this step if you already installed Homebrew or other package manager

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2.2 Install CMake

$ brew install cmake

3.Get source code

3.1 Go to the directory where you want to download source code

I used my Desktop folder in this post. You can change it as you want.

$ cd ~/Desktop

3.2 Download source code from git repository

$ git clone https://github.com/ethereum-mining/ethminer.git

3.3 Go to the source code directory

$ cd ethminer

4. Build from source code

4.1 Create a build directory

$ mkdir build; cd build

4.2 Configure the project with CMake

$ cmake ..

If you have NVidia GPU(s), you need to add more options
$ cmake .. -DETHASHCUDA=ON

4.3 Build the project using CMake Build Tool Mode

$ cmake --build .

You will get the result like below if you succeeded.

Don't worry about the 'warning's.

5. Start mining

The executable file generated at ~/Desktop/ethminer/build/ethminer/. So go to that directory to run the miner.

$ cd ~/Desktop/ethminer/build/ethminer/

For dwarfpool

./ethminer -G -F http://eth-eu.dwarfpool.com/<YOUR_ETH_WALLET_ADDRES>

For ethermine pool

./ethminer --farm-recheck 200 -G -S eu1.ethermine.org:4444 -FS us1.ethermine.org:4444 -O <YOUR_ETH_WALLET_ADDRES>.<YOUR_RIG_NAME>

You should change <YOUR_ETH_WALLET_ADDRES> and <YOUR_RIG_NAME> to your own ones.

Nvidia users need to change -G to -U.

This is the result from my laptop (AMD 460).

It shows almost 6 MH/s. It's definitely better result than from my previous post (1.5 MH/s).
The good news is that you can boost this number a little bit. I'll write about it on my next post.

For advanced users

$ ./ethminer --help

will show you more detailed options that you can tweak.

For Nvidia users

I don't have Nvidia GPUs on my Mac, so I'm not sure the followings are needed, but try installing all of them if you have any troubles.

The latest NVIDIA CUDA driver

https://www.nvidia.com/object/mac-driver-archive.html

The "web" driver appropriate for your macOS version

El Capitan: 10.11.6.

http://www.nvidia.com/download/driverResults.aspx/114670/en-us

Sierra: 10.12.3

http://www.nvidia.com/download/driverResults.aspx/117892/en-us

Please let me know

If you tried this, share your result with your hardware specs.
I know the Mac isn't the good machine for just mining purpose, but I did this for my curiosity.
