This is a really cool project. I just tried to compile it myself, and code-signed it with my mac dev key. I changed the assets/sekey.entitlements file by replacing 5E8NNEEMLP with my own hex id for my developer key.
However, when i run ./bundle/Sekey.App/.../sekey, i keep getting a "Killed 9" message.
When i run the unsigned version, the binary at least runs (shows the -h messages). Any hints on how to fix?
