You can distribute Mac software without paying Apple. or having signed code It just requires users to open it using their password
If you want to walk through it with me, I'd be happy to compile it and let you upload it for others to use too. My main concern is that there are going to be compilation issues and without realtime help, it's just going to be a waste of energy because compilation instructions on open source software never seem to work. I'm not sure if it's because the different OS software has slight differences or what, but it's an issue I ran into 100% of the times I tried to do it
