Unzip the Ignition download file and install Ignition into /usr/local/ignition by running the following command:
unzip <<ignition-macosx.zip>> -d /usr/local/ignition

where <<ignition-macosx.zip>> is the path to the Ignition Mac OS X distribution you downloaded.

cd /usr/local/ignition
Make the files executable by executing the following three chmod commands:
chmod +x ignition.sh
chmod +x ignition-gateway
chmod +x gcu.sh
To turn the application into a service, create a symlink to ignition.sh in /usr/local/bin
cd /usr/local/bin
ln -s /usr/local/ignition/ignition.sh ignition
chmod +x ignition
To start Ignition now, type
