Change Jenkins default port on Mac

If you want to run Jenkins locally on Mac OS X and change default port 8080 you have to change httpPost parameter using following command:

sudo defaults write /Library/Preferences/org.jenkins-ci.plist httpPort 9000

 After that you have to restart Jenkins:

sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist
sudo launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist

Thats it.
