Another alpha release, this time with a signed OS X app that does not require libzmq to be installed on the system. 🎉
However, there's a bug where an error will occur on the first time you launch nteract. You can launch again freely after that. We're digging into it.
No built in kernel, you will need kernels to be installed directly to run nteract:
python3 -m pip install ipykernel
python3 -m ipykernel install --user
