Unable to get Flow emulator running

I am attempting to run a Flow emulator on my MacBook air in accordance with this article: How to Create NFTs Like NBA Top Shot With Flow and IPFS | by Justin Hunter | Pinata | Medium

The smart contract runs perfectly well on the playground but when I try to run:

flow project start-emulator

It gets stuck and never starts:

I would appreciate any advice

Have you had any success in fixing this? I’m having the same exact problem.

The log states that emulator has been started and is listening on stated ports.
What is that you expect?
