Lauching Keychain Minder with a LaunchAgent

I do this and it works great for me. Here is the postflight script I use to install it with a package. Just make an installer package and install Keychain Minder in /Applications/Utilities. Change com.yourcompany in the script to whatever your orgs name is if you want.

#!/bin/sh

# Install Keychain Minder and a Launchd item so it starts for every user.

# Declare 'defaults'and 'PlistBuddy'.

defaults="/usr/bin/defaults"
PlistBuddy="/usr/libexec/PlistBuddy"

# Declare our working directories.

PKG_DIR="$1/Contents/Resources"
APP_DIR="$3/Applications/Utilities"
LAUNCHD_DIR="$3/Library/LaunchAgents"

# Install Launchd item to /Library/LaunchAgents.

$defaults write "${LAUNCHD_DIR}/com.yourcompany.keychainminder" Label com.yourcompany.keychainminder
$defaults write "${LAUNCHD_DIR}/com.yourcompany.keychainminder" ProgramArguments -array
$PlistBuddy -c "Add :ProgramArguments:Item\ 1 string /Applications/Utilities/Keychain\ Minder.app/Contents/MacOS/Keychain\ Minder" "${LAUNCHD_DIR}/com.yourcompany.keychainminder.plist"
$defaults write "${LAUNCHD_DIR}/com.yourcompany.keychainminder" RunAtLoad -bool YES

# Give Launchd item correct permissions.

chown root:wheel "${LAUNCHD_DIR}/com.yourcompany.keychainminder.plist"
chmod 644 "${LAUNCHD_DIR}/com.yourcompany.keychainminder.plist"
