-
java -jar /Users/build-user/Jenkins/agent.jar -jnlpUrl https://****/jenkins-agent.jnlp -secret **** -workDir "/Users/build-user/Jenkins"is running on a Unix agent, version 4.13.3.

I have not changed the Mac（agent） settings. I just updated jenkins(controller).
If anyone knows how to resolve this, please let me know.
