After upgrading my macOS to Sierra, when I start Jenkins using launchctl load I cannot connect to localhost:8080. If I call launchctl load again, I see response "service already loaded". There is no log file at the default location /var/log/jenkins/ (as set in jenkins-ci.plist). I also tried to create jenkins.log there and chown to jenkins user, but still nothing is printed there.

If I try to start Jenkins using java -jar jenkins.war, I can connect to localhost, but Jenkins runs as a new installation.

I have the latest JRE 1.8.0_102 installed.

How to diagnose the problem?

Seems that Sierra changed the permission of Jenkis folder. So the best solution is:
1. Add execute permissions to org.jenkins-ci.plist:
sudo chmod +x /Library/LaunchDaemons/org.jenkins-ci.plist
2. Set jenkins as the owner of /var/log/jenkins:
sudo chown jenkins /var/log/jenkins
3. Start Jenkins:
sudo launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist
