Problem Description

The issue was reported by a community user in Discuss (c.f https://discuss.elastic.co/t/incomplete-jdk-app-in-the-installation-package-unable-to-start-elasticsearch-macos-x86-64-elasticsearch-8-13-2/357275) and observed in our environment as well.

In https://www.elastic.co/guide/en/elasticsearch/reference/current/targz.html#install-macos, we will need to include a similar content as the macOS Gatekeeper warnings provided in the Kibana documentation page (https://www.elastic.co/guide/en/kibana/current/targz.html#install-darwin64)

Steps to Reproduce

c.f above

Do we understand the cause of this? Is there something we can change in how we package/sign our artifacts to avoid such a thing?

Hi @mark-vieira

Do we understand the cause of this? Is there something we can change in how we package/sign our artifacts to avoid such a thing?

To be honest, I am not entirely sure. I am not familiar with the Apple notarization process and macOS Gatekeeper.

In the meantime (while we assess a possible technical resolution), it will be great to add the important note in our Elasticsearch documentation (with a similar content as what the Kibana team did).
