The title pretty much says it all. OrientDB has an official image which as of this writing was updated 4 days ago, so why make work for yourself?
docker pull orientdb
How hard is that? Details can be found at https://hub.docker.com/_/orientdb/ , and of course at https://orientdb.com/ .
Details on setting up Docker on your Mac (or Linux, or Windows), can be found at https://www.docker.com/get-docker
For a lot of tools like this, Docker just seems the easier and better solution.
