This is probably very simple, but I can\'t find any hint anywhere. So how one is supposed to do that, in general and specifically on Mac?
Run the following commands to completely uninstall Jenkins from MacOS Sierra. You don't need to change anything, just run these commands.
sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist
sudo rm /Library/LaunchDaemons/org.jenkins-ci.plist
sudo rm -rf /Applications/Jenkins '/Library/Application Support/Jenkins' /Library/Documentation/Jenkins
sudo rm -rf /Users/Shared/Jenkins
sudo rm -rf /var/log/jenkins
sudo rm -f /etc/newsyslog.d/jenkins.conf
sudo dscl . -delete /Users/jenkins
sudo dscl . -delete /Groups/jenkins
pkgutil --pkgs
grep 'org\.jenkins-ci\.'
xargs -n 1 sudo pkgutil --forget
