1. Download archive from "https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.DownloadingAndRunning.html"
2. Unpack it to: `/opt/aws/dynamodb`
3. Create shell script: `/opt/aws/dynamodb/dynamodb_local.sh`.
   
   ```sh
   #!/bin/bash

   RootDirPath=$(cd "$(dirname "$0")"; pwd)
   cd "$RootDirPath"

   java -Djava.library.path="$RootDirPath/DynamoDBLocal_lib" -jar "$RootDirPath/DynamoDBLocal.jar" "$@"
   ```
 
4. Update `PATH` variable: `export PATH="$PATH:/opt/aws/dynamodb"`
5. Run `dynamodb_local.sh -help`
6. Run `/opt/aws/dynamodb/dynamodb_local.sh -sharedDb -port 6320 -dbPath /opt/mca/dynamodb`
7. Test the instance `aws dynamodb list-tables --endpoint-url http://localhost:6320`
8. Create file `~/Library/LaunchAgents/mca.dynamoDBLocal.plist`

    ```xml
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
        <key>Label</key>
        <string>mca.dynamoDBLocal</string>
        <key>LimitLoadToSessionType</key>
        <array>
            <string>Aqua</string>
            <string>Background</string>
            <string>LoginWindow</string>
            <string>StandardIO</string>
            <string>System</string>
        </array>
        <key>ProgramArguments</key>
        <array>
            <string>/opt/aws/dynamodb/dynamodb_local.sh</string>
            <string>-sharedDb</string>
            <string>-port</string>
            <string>6320</string>
            <string>-dbPath</string>
            <string>/opt/mca/dynamodb</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>WorkingDirectory</key>
        <string>/opt/aws/dynamodb</string>
        <key>StandardErrorPath</key>
        <string>/opt/mca/dynamodb/dynamodb-stderr.log</string>
        <key>StandardOutPath</key>
        <string>/opt/mca/dynamodb/dynamodb-stdout.log</string>
    </dict>
    </plist>
    ```
9. Run as macOS service ```launchctl bootstrap user/`id -u` $HOME/Library/LaunchAgents/mca.dynamoDBLocal.plist```
10. Get status: ```launchctl print user/`id -u`/mca.dynamoDBLocal```
11. Unload macOS service if not needed anymore: ```launchctl bootout user/`id -u`/mca.dynamoDBLocal```
