Hi
No problem in my environment.
My MacOS is High Sierra (10.13.6).
I've tried both "Enable offline mode" on and off.

could you share details of your HTTP/PROXY setting.
I was using HTTP. Changed it to NO PROXY. Could you share the details please. Really appreciate

Proxy Settings: No Proxy
Neo4j version: 3.5.15

Thanks. I just reinstalled with these settings
