McCain X1 Source Available

[Steppenwolf]

One additional (maybe not as an expert) remark.
I have read that the Coda-nvidia-driver is not available for Mojave. Is there any additional solution to use the power of mac?

Dear MikeB,

your efforts are very much appreciated!
One simple naive question: why do I have to use use macports or brew to be installed?
I also do not use these libraries when running the mac-binary of Stockfish?

Attached below is a link to download an Lc0 macOS engine - see if that works, if it does not work you must build your own engine ( which was stated on the Lc0 getting started page). If you going to build your own Lc0 Mac engine , you must install macports or homebrew - there is no way around it.

"Mac
Install brew as per the instructions at https://brew.sh/
Install python3: brew install python3
Install meson: brew install meson
Install ninja: brew install ninja
When using Mojave install SDK headers: installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
Run ./build.sh
The resulting binary will be in build/release"

It will enables you to rebuild Lc0 whenever there is an update at your desire"

Scroll down to the bottom to see Mac instructions
https://github.com/LeelaChessZero/lc0

From then on - you simply run step 6 ->Run ./build.sh" to refresh.

Now some of that may seem a little bit intimating for a newbie in this endeavor - but I can walk you through the steps. It's quite simple really.

On this question:

"One additional (maybe not as an expert) remark.

To use the GPU of your mac - you must have a GPU that OpenCL compliant - most recent Macs ( 2015 and later - some earlier - depends on the model) are Open CL compliant - On an older 2010/2012 MacPro - its quire simple to install a GPU upgrade> I believe the 2013 Mac Pro models would be compliamt. You might get 35 70 nps using just your CPU, depending on the GPU , you will see 500 to 700 nps (or more if you have a really good GPU. Both my 2015 iMac and Mac Pro see about 500 to 700 nps. Recent models should see more. It's true the Cuda-nvidia-driver for GPU is not available for Mojave - but I believe most recent Macs will work with Open CL even on Mojave ( I am on Mojave).

Thanks MikeB,

I will try out now.
How/where can I see the nps of my CPU resp. GPU on my Mac?

Thanks.

#1 .. your compile has issues or should I say my Mac has

(build/release >> is it a folder ??)

Unzip the the attached zip file and place it under the subprojects/protobuf-3.5.1 folder as shown. If you move the lc0 executable to a different folder, copy the entire subproject folder to the same folder as show - note lc0 is at the same directory level as the subproject folder.

Forum would not allow me to place and attachment file and two snapshots in the same post - thus the 3 posts.

(build/release >> is it a folder ??) -> yes, but you will not see it until after a successful build

zsh: no such file or directory: ./build.sh -> not sure why , but I never use zsh , you might want to try bash - type "bash -l" at the command prompt , type "zsh" again to go back again. I'm just guessing , I'm not a shell expert by any means. You might have to change build.sh permissions to run, "chmod 755 build.sh" ?

dyld: Library not loaded: @rpath/libprotobuf-lite.dylib - see my posts above ..( which I think you have seen already)
