What's new in macOS 1.34.0​

Native LaunchDaemon mode for macOS​

The macOS delegate now supports running as a system-level service (LaunchDaemon) in addition to the existing user-level service (LaunchAgent). LaunchDaemon mode starts the delegate at system boot without requiring a GUI session, making it suitable for EC2 macOS instances and environments where auto-login is prohibited by security policies.

To install in LaunchDaemon mode, use the --mode=system and --user flags with sudo:

sudo ./delegate install --account=[Your Account ID] \
                        --token=[Your Delegate Token] \
                        --url=[Your Harness URL] \
                        --name=[Your Delegate Name] \
                        --mode=system \
                        --user=[Your macOS Username]

All LaunchDaemon operations require sudo because the delegate interacts with the system domain (/Library/LaunchDaemons/) instead of the user domain. The workspace directory for daemon mode is /opt/harness-delegate/.

For complete installation instructions, go to Install Harness Delegate on a Local Machine — LaunchDaemon mode.
