Some time ago I made a portable version for windows. I installed DT on my local machine and then added a config folder to the installed directory… THis was on Windows… THen I ran a little batch file that just ran DT pointing to the config… by doing this way you could unzip and run it from anywhere including a USB drive… I suspect you can do the same on Mac… THe key was to add the config folder and then run DT using a batch with the --configdir parameter and point it to that local config file…
