 If you would like to run OpenSearch with a particular plugin installed on the cluster snapshot, pass the `--P` flag after `yarn opensearch snapshot`. You can use the flag multiple times to install multiple plugins. The argument value can be a URL to the plugin's zip file, maven coordinates of the plugin, or a local zip file path (use `file://` followed by the absolute or relative path, in that case).

 ### Alternative - Run OpenSearch from tarball
 
-OpenSearch does not yet create artifacts for MacOS, so you'll need to download, install, and run the tarball instead. (You'll also need Java installed and the `JAVA_HOME` environmental variable set - see [OpenSearch developer guide](https://github.com/opensearch-project/OpenSearch/blob/main/DEVELOPER_GUIDE.md#install-prerequisites) for details).

 1. Download the latest minimal distribution of OpenSearch from [the downloads page](https://opensearch.org/downloads.html#minimal). Note the version and replace in commands below.
 2. Unzip the `tar.gz` file: `tar -xvf opensearch-<OpenSearch-version>-linux-x64.tar.gz`
