Couchbase enterprise_5.1.1-macos on sierra

Hello,

I downloaded the latest server version (enterprise_5.1.1) form mac. Followed the installation steps but server is not starting and get this message.

“Couchbase server doesn’t seem to be operating properly. check console logs for more details”

Any help with the error? Where can I see the console log? ~/Library/Application Support/Couchbase does not have any logs.

Thanks,
Rajeev
