The CaraOne client configuration file is located at ~/Library/Application Support/com.ObviousFuture.CaraOne/caraone.json on a mac.  If those directories and files don't exist you have to launch CaraOne on the computer for the first time so they can get greated.

You can copy that .json file from your working mac client and put it on new machines to complete installations quicker.  If the .json exists already on new macs you are deploying, you can either delete the existing .json file or just rename it to something else if you prefer.
