Launchctl:Dubious permissions on file: Problem Installing Jenkins
If you're in /Library/LaunchDaemons, which I assume you are for a system daemon, and want the files to go back to default:

sudo chown root:wheel org.jenkins-ci.plist
sudo chmod 644 org.jenkins-ci.plist


The plist will register on reboot, or you can load it like this:

sudo launchctl load org.jenkins-ci.plist


You can check the status like this:

sudo launchctl list &lt;&lt;Job Name&gt;&gt;


Note that jobname is not the same as file name. Inside the plist you'll see a Label. That's the name:

    &lt;key&gt;Label&lt;/key&gt;
    &lt;string&gt;DataScrub&lt;/string&gt;


In my example the name is DataScrub, so would be:

sudo launchctl list DataScrub
