I haven't gotten around to adjusting the parts needed for the R606 to run on macOS yet.
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?
