I have a script monta.sh to mount an external volume:

#!bin/sh
mkdir -p /Volumes/remvol
mount_smbfs //user:password@server/folder /Volumes/remvol

Then I have a com.jo.monta.plist to launch the script after system boot placed in /Library/LaunchDaemons:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.jo.monta</string>
    <key>Disabled</key>
    <false/>
    <key>UserName</key>
    <string>admin</string>
    <key>ProgramArguments</key>
    <array>
        <string>/Users/admin/scripts/monta.sh</string>
    </array>
    <key>KeepAlive</key>
    <dict>
        <key>SuccessfulExit</key>
        <false/>
    </dict>
    <key>RunAtLoad</key>
    <true/>
</dict>
</plist>

I've tested the script from the command line and it works, however if I log in after boot the volume is not mounted.

It seems like the plist file doesn't load? what's wrong?

  • Small correction to the script: #!bin/sh should be #!/bin/sh – Graham Miln Feb 29 '16 at 8:14
  • Do you see any output in system.log regarding this launchd job? You can see the contents of system.log using Applications > Utilities > Console.app. – Graham Miln Feb 29 '16 at 8:16
  • @GrahamMiln Thanks, I corrected my script. I haven't seen any reference to com.jo.monta in the system log, I have also used launchctl list | grep monta to see if there was something and no reference neither. – naio Feb 29 '16 at 8:45
  • Why are you using ProgramArguments instead of Program (which is a simple key/value pair, not an array, see man launchd.plist for details)? – nohillside♦ Feb 29 '16 at 9:31

The script and the plist work perfectly well if you make following changes:

add a slash in /Users/admin/scripts/monta.sh:

#!/bin/sh
mkdir -p /Volumes/remvol
mount_smbfs //user:password@server/folder /Volumes/remvol

proper ownership of com.jo.monta.plist:

sudo chown root:wheel /Library/LaunchDaemons/com.jo.monta.plist

proper file mode bits of /Users/admin/scripts/monta.sh:

chmod 755 /Users/admin/scripts/monta.sh

load the launch daemon:

sudo launchctl load /Library/LaunchDaemons/com.jo.monta.plist

  • @naio Try chmod 755 /Users/admin/scripts/monta.sh – klanomath Feb 29 '16 at 14:04
