macOS Startup Item for all users

[shuggans]

Completely new to Macs here, but I am trying to figure out how to create a startup item for all users that will launch a shell script at login.

From what I understand... I need to use launchd to create a launch agent by placing a plist file into the /Library/LaunchAgents directory - but when I do this the script is not executed (+x has been set on the script) at login.

I am also using el capitan - which I keep finding out has a bunch of things disabled in it.

Am I even going the right direction with this?

The plist file must be owned by root. To change it:

sudo chown root /Library/YOUR_PLIST_NAME_HERE.plist

The plist file must also be no-write to group and to world.

See here, find "owned" on page:

So what is root isn't launching the process? I need any user who uses the mac to have this script run under their user account at logon... from what I gather of the documentation, that is exactly what the /Library/LaunchAgents directory is for... do plists in there still need to be owned as root?

I made root the owner, and set 644 on the plist - still nothing at logon.
