If you want it to try to run it there, you'll need to make an adjustment to use the R606 branch:
curl -o cgminer.rb "https://raw.githubusercontent.com/vthoang/homebrew-cgminer/master/cgminer.rb"
edit the cgminer.rb file and change branch from 'master' to 'r606'
followed with:
brew install --build-from-source ./cgminer.rb
I'll get around to testing that when the branch gets merged back. At which point it should mostly fix itself.
I got around to trying this today and i can confirm this works. As of now my R606 is hashing at a stable 740 ghs under mac os 10.13
Full order of commands needed to get R606 to work on mac:
curl -o cgminer.rb "https://raw.githubusercontent.com/vthoang/homebrew-cgminer/master/cgminer.rb"
Followed by:
nano cgminer.rb
Change the value of branch in the file to "R606" and save then exit.
Then build from source by running:
brew install --build-from-source ./cgminer.rb
Is there a way to disable the autotune frequency setting for the R606?
