Hi @izgabel,

Please post stacktraces as text inside code blocks (triple back-ticks).

The error I see there is that netty is only supported on Linux. You may need to rebuild some module. See here: https://netty.io/wiki/native-transports.html

Please open a GitHub issue for “Cannot build on Mac OS” in the Zeebe GitHub project if you can’t get that to work.

Josh

@jwulf Thanks for your reply.

I’ve read this article before and it doesn’t seem to help.
