Confused on version and installing Java JDK for Mac to support Enterprise for OnLine learning class

Trying to take the on-line course for managing Neo4j and it wants me to have Enterprise installed. That requires Java JDK to be installed on my Mac. Not a Java user I am totally confused by the Java versions and then how to install on Mac without breaking the Mac. Is there a set of instructions for how to do this? Otherwise, I am fine just using Neo4j Desktop for learning.

Neo4j Desktop includes a developer-licensed version of Neo4j Enterprise, so you're fine to use that as-is.

Ok, but where do I find it? I have the Neo4j Desktop.app file, but cannot find file loctions as shown in 4.2 of Operations manual. Buried in /Users/bbrown/Library/Application Support/Neo4j Desktop I have installation-3.5.3 and the bin folder. If I try * sudo bin/neo4j start then I get 'Unable to find any JVMs matching version "1.8".' So in the module Module: Managing a Neo4j Database, I am stuck on Managing a Neo4j Instance. Am I in the wrong place?

I'm having the same problem. still can't start community edition on my mac, any luck with this? I installed Java 1.8 but still same error.
