@Sjoerd Thanks for your answer, this is what worked for me. To be still clearer, here's what I did in terminal on Anaconda 3 on High Sierra:

echo "ipykernel 4.10.0" >> ~/anaconda3/conda-meta/pinned

conda update anaconda

When I tried to update only ipykernel, I would have dependencies errors. By updating anaconda, everything is now up to date but ipykernel which is effectively at version 4.10.0. I didn't experience any hang since then.
