Save the launch daemon as in /Library/LaunchDaemons/ and owned by root:wheel. usr/bin is recommended if brew is installed. and owned by root:wheel with sudo chown root:wheel. So put your shell script my_script.sh in /usr/local/bin/ or in /usr/bin/ (adjust the path in the ProgramArguments array if you use the latter), make it executable with sudo chmod +x. ![]() A launch daemon in /Library/LaunchDaemons is already executed with root privileges so you may omit the UserName part. Here is what I have in my LaunchDaemons folder: Ī ~/Library/LaunchDaemons doesn't exist. The file I want to run as root is: "/Users/CURRENT_USER/Dev/my_script.sh" As a last try, I even tried Automator with no luck. I've made a launch daemon, which is allegedly the root functions, but that's no luck either. Then I've been pulling my hair trying to use the launchd function. Like this: chown root theProgram chmod 4755 theProgram The 4 says that anyone can execute the file and anyone doing so will do it as root. bash_profile, etc that route got me no where. In this case, you'll want to set the file as owned by root and then change its permissions to run the file as the file's owner. Agents are useful because they can do things that daemons can't, like reliably access the user's home directory or connect to the window server.I've tried everything and can't seem to get my script to run at startup.

Sudo launchctl load /Library/LaunchAgents/ist Property lists in LaunchAgents also work, but you have to load both agents and daemons with sudo: sudo chown root /Library/LaunchAgents/ist sudo chown root:admin script_to_run_by_launchd Ever think of giving ownership of the script to root using chmod? This way, it won't run unless run as root. To make sure it is run as root, I'm pretty sure launchd will run the programs as root. Lingon (abandoned, but supposedly works on Leopard and Snow Leopard).Have you tried using one of the launchd editors? sudo launchctl load -w /Library/LaunchDaemons/)Ĭheck out man launchd for more information. You can not use setuid to change the user running the script on daemons.īecause you will want to add it in /Library/LaunchDaemons you will want to make sure you load it into launchd with administrator privileges (eg. Launch Agents ( /Library/LaunchAgents/ or ~/Library/LaunchAgents/) are run when a user is logged in as that user.
