I previously install 7.12 on my Mac with Brew, after upgrade to 7.15, Kibana failed to start with below error:
FATAL Error: Unable to complete saved object migrations for the [.kibana] index. Please check the health of your Elasticsearch cluster and try again.

What do the Elasticsearch logs show? How much disk space do you have?

Hi, I managed to resolve it by removing old install files and re-install 7.1.5, thanks
rm -R /usr/local/var/lib/Elasticsearch/\*
rm -R /usr/local/var/lib/kibana/\*
