For the successful setup of CGMiner for the Compac A1 for Mac, I recommend the following operating system versions and extensions<\/p>\n\n
The first step is to install the Apple Command Line Tools on your Mac OS operating system. Open the Terminal app and enter the following to install the Apple Command Line Tools:<\/p>\n\n
xcode-select --install<\/code><\/pre>\n\nInstall package manager and resolve package dependencies<\/h3>\n\n
First, the free package manager Homebrew (https:\/\/brew.sh<\/a>) for Mac OS must be installed. This takes 5-10 minutes, depending on the speed of your internet connection.<\/p>\n\n\/bin\/bash -c \"$(curl -fsSL https:\/\/raw.githubusercontent.com\/Homebrew\/install\/HEAD\/install.sh)\"\nbrew analytics off<\/code><\/pre>\n\nThe following packages must be installed to resolve the package dependencies of CGMiner:<\/p>\n\n
Build<\/h3>\n\n
For the Mac, Kano has a prepared “recipe” (tap) in Homebrew:<\/p>\n\n
brew tap kanoi\/cgminer\nbrew install cgminer<\/code><\/pre>\n\nIf you already use Homebrew as a package manager on your Mac, you can follow these steps to update Hombrew and install CGMiner:<\/p>\n\n
brew analytics off\nbrew doctor\nbrew update\nbrew upgrade\nbrew cleanup\nbrew tap kanoi\/cgminer\nbrew install cgminer<\/code><\/pre>\n\nTo install smaller updates of CGMiner (with an already current Homebrew installation, the following command is sufficient:<\/p>\n\n
brew reinstall cgminer<\/code><\/pre>\n\nAfterwards, I recommend testing the newly compiled binary as follows:<\/p>\n\n
sudo cgminer -n<\/code><\/pre>\n\nThis command lists the detected miners. Example output \u201cCompac F BM1397 Bitcoin Miner\u201d.<\/p>\n\n
Setup<\/h3>\n\n
I recommend setting up a configuration file, it is much clearer than starting CGMiner with console parameters.<\/p>\n\n
Example of a gekko.conf configuration file:<\/h4>\n\n{\n\"pools\" : [\n{\n\"url\" : \"stratum+tcp:\/\/stratum.kano.is:3333\",\n\"user\" : \"benutzername.worker\",\n\"pass\" : \"x\"\n}\n],\n\"gekko-compaca1-start-freq\" : \"300\",\n\"gekko-compaca1-freq\" : \"300\",\n\"gekko-compaca1-corev\" : \"300\",\n\"gekko-compaca1-detect\" : true,\n\"gekko-r909-freq\" : \"450\",\n\"gekko-r909-detect\" : true,\n\"gekko-compacf-freq\" : \"400\",\n\"gekko-compacf-detect\" : true,\n\"gekko-tune2\" : \"60\",\n\"suggest-diff\" : \"442\",\n\"failover-only\" : true,\n\"api-listen\" : true,\n\"api-port\" : \"4028\",\n\"api-allow\" : \"W:192.168.1.0\/24,W:127.0.0.1\"\n}<\/code><\/pre>\n\nHow to start CGMiner with configuration file:<\/p>\n\n
cgminer -c gekko.conf <\/code><\/pre>\n\nThis is how the command line looks like without a configuration file<\/p>\n\n
cgminer --o stratum+tcp:\/\/stratum.kano.is:3333 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr -p x --suggest-diff 442 --gekko-compacf-freq 400 --gekko-compacf-detect true<\/code><\/pre>\n\nIn the examples above, please replace the pool data as well as the user name and worker with your own pool data, user data and worker.<\/p>\n\n
Depending on the intended use, it is recommended to log the output of CGMiner in a log file:<\/p>\n\n
cgminer -c gekko.conf 2> \"run-`date +%Y%m%d%H%M%S`.log\"<\/code><\/pre>\n\nAlternatively, you can put CGMiner into a shell script that writes a log file:<\/p>\n\n
touch cgminer.sh\nsudo nano cgminer.sh<\/code><\/pre>\n\nContent of the shell script:<\/p>\n\n
#!\/bin\/sh\n#\nwhile true ; do\nnow=\"`date +%Y%m%d%H%M%S`\"\n#\n.\/cgminer -c gekko.conf \"$@\" 2> \"run.$now.log\"\n#\necho \"Sleeping for 5 seconds ...\"\nsleep 5\ndone<\/code><\/pre>\n\nThen make the shell script executable:<\/p>\n\n
chmod +x cgminer.sh<\/code><\/pre>\n\nThe \u201c$@\u201d means that you can pass additional parameters to the shell script to be added to the running cgminer, e.g. to disable asicboost.<\/p>\n\n
cgminer.sh --gekko-noboost<\/code><\/pre>\n\nAccessing the API on Mac<\/h3>\n\n
Install Java for Mac. Oracle suggests the correct version of Java for desktop applications. Make sure you select the correct Java installation package for Intel or Apple Arm64 CPU.<\/p>\n\n
https://java.com\/<\/code><\/pre>\n\nPlease make sure that you have enabled the API functionality in the configuration file or via the console parameter:<\/p>\n\n
--api-enable --api-allow \"W:127.0.0.1\"<\/code><\/pre>\n\nFinally, you can test the Java API functionality on your Mac. Please enter the following in a terminal window<\/p>\n\n
cd Library\/Caches\/Homebrew\/cgminer--git\/\njava API estats<\/code><\/pre>\n\nAccessories<\/h3>\n\n
In particular, to operate the miner with a Raspberry Pi, it requires a USB hub with an active power supply that is able to provide at least 3 A per USB port. We have had good experiences with USB 2.0 devices from Anker and Orico. Our 7-port USB hub<\/a> has self-resetting fuses on each port and can provide up to 6 amps per port.<\/p>\n\n
