Hello,
I would appreciate someone's help with with displaying a simple pop up/notification message to a user after a LaunchDaemon has succesfully run. It has to be a Launchdaemon and not a Launchagent.
I have the plist and script in place and its works great but I now need to be shown how to display a message to an end user.
thanks

What is that script written in, and why not add a notification solution as the last activity in the script? I have a short example in PyObjC, and a Bash script that uses a function with arguments to use AppleScript's display notification dialog.
Hi VikingOSX
The script is a bash script, here it is.
The osascript below does not display the message.
I don't know how to do add what you say, should that in theory work?
#!/bin/bash
Version=$(sw_vers | grep ProductVersion | tail -c 7 | cut -d . -f 2)
if [ $Version -ge 12 ]
then
launchctl unload /Library/LaunchDaemons/net.sierra.plist
rm -f /Library/LaunchDaemons/net.sierra.plist
rm -f /usr/local/bin/sierra.sh
exit 0
else
rm -rf /Applications/Install\ macOS\ Sierra.app/
osascript -e 'tell app "System Events" to display dialog "macOS Sierra is not allowed on computers at this time." with title "Technology Notice" buttons {"OK"} default button "OK" giving up after 30'
fi
There is nothing wrong with your osascript and AppleScript syntax. If the rm fails, it will do so quietly and the osascript never gets run. I added a conditional to check if the installer exists before trying to remove it, in which case, if it does exist, the osascript gets run. Also, you might consider setting the tail -c 7 to tail -c 8.
Change:
else
rm -rf /Applications/Install\ macOS\ Sierra.app/
osascript -e ...
fi
to:
elif [ -d /Applications/Install\ macOS\ Sierra.app ]
then
rm -rf /Applications/Install\ macOS\ Sierra.app
osascript -e ...
fi
If you wanted the slide in notification, then you would use display notification syntax.
Hello
You'd need to have application "System Events" be at front lest its dialogue is hidden behind.
#!/bin/bash osascript -e 'tell application "System Events" activate display dialog "macOS Sierra is not allowed on computers at this time." with title "Technology Notice" buttons {"OK"} default button 1 giving up after 30 end tell'
or
#!/bin/bash osascript <<'EOF' tell application "System Events" activate display dialog "macOS Sierra is not allowed on computers at this time." with title "Technology Notice" buttons {"OK"} default button 1 giving up after 30 end tell EOF

I changed the script to what you have written and the sierra.app deletes but there is still no notifcation message.
I would add that IF i create a test directory /Applications/Install macOS Sierra.app it deletes AND I get the message too??
Hi H
thanks for the reply.
I am not sure where that goes in the script but i tried both suggestions but nothing happened. The .app did not delete niether did i get a pop up message.
Check console messages for any clues.
I checked the log at the point where the disaply message should appear. Does this make any sense to anyone?
com.apple.xpc.launchd[1] (com.apple.xpc.launchd.domain.system): Could not import service from caller: caller = osascript.1115, service = com.apple.systemevents.42912, error = 134: Service cannot load in requested session
Incorporate Hiroto's osascript HERE syntax will display the message if the Sierra installer is present. The '¬" symbol is a statement continuation character (option + L) for formatting improvement.
#!/bin/bash
Version=$(sw_vers | grep ProductVersion | tail -c 7 | cut -d . -f 2)
if [ $Version -ge 12 ]
then
echo "Do Sierra related stuff"
elif [ -d /Applications/Install\ macOS\ Sierra.app ]
then
# rm -rf /Applications/Install\ macOS\ Sierra.app
osascript <<'EOF'
tell application "System Events"
activate
display dialog "macOS Sierra is not allowed on computers at this time." ¬
with title "Technology Notice" buttons {"OK"} default button 1 giving up after 30
end tell
EOF
fi
exit 0
Hmm. I'm not sure but I'd guess your script is run in an environment with no connection to window server. I'd try the following that executes osascript by a user who is running an instance of SystemUIServer and thus has connection to window server.
#!/bin/bash # get uid who is running an instance of /System/Library/CoreServices/SystemUIServer.app/Contents/MacOS/SystemUIServer uid=$(ps -ax -o uid,command | awk '/MacOS\/SystemUIServer/ {print $1}' | head -n1) # if no such uid is found, exit [[ -n $uid ]] || exit # execute osascript by user of the uid sudo -u "#$uid" osascript <<-'EOF' tell application "System Events" activate display dialog "macOS Sierra is not allowed on computers at this time." with title "Technology Notice" buttons {"OK"} default button 1 giving up after 30 end tell EOF
* You may replace your osascript line with the codes above.
Good luck,
H
I'm not sure I am understanding that when you say
then
echo "Do Sierra related stuff"
I did try your script with what i thought was right but it did not delete the .app or display the message.
thanks again.
#!/bin/bash
Version=$(sw_vers | grep ProductVersion | tail -c 7 | cut -d . -f 2)
if [ $Version -ge 12 ]
then
echo "Do Sierra related stuff"
elif [ -d /Applications/Install\ macOS\ Sierra.app ]
then
# rm -rf /Applications/Install\ macOS\ Sierra.app
osascript <<'EOF'
tell application "System Events"
activate
display dialog "macOS Sierra is not allowed on computers at this time." ¬
with title "Technology Notice" buttons {"OK"} default button 1 giving up after 30
end tell
EOF
fi
exit 0
Its all Mac users (that have admin rights)
Sorry H I'm not sure what or where that goes in my script at the top of the page.
thanks again.
Ok I have amended it to the below. But unfortunately there is still no display message but the sierra.app did delete upon download. Again I would add if I make a test directory /Applications/Install\ macOS\ Sierra.app it deletes and you get the display message.
#!/bin/bash
Version=$(sw_vers | grep ProductVersion | tail -c 8 | cut -d . -f 2)
if [ $Version -ge 12 ]
then
launchctl unload /Library/LaunchDaemons/net.sierra.plist
rm -f /Library/LaunchDaemons/net.sierra.plist
rm -f /usr/local/bin/sierra.sh
exit 0
elif
[ -d /Applications/Install\ macOS\ Sierra.app ]
then
rm -rf /Applications/Install\ macOS\ Sierra.app
osascript <<'EOF'
tell application "System Events"
activate
display dialog "macOS Sierra is not allowed on computers at this time." ¬
with title "Technology Notice" buttons {"OK"} default button 1 giving up after 30
end tell
EOF
fi
exit 0
I meant you might try something like the following. (I'm not responsible for other parts than the osascript related 😉 )
#!/bin/bash Version=$(sw_vers | grep ProductVersion | tail -c 7 | cut -d . -f 2) if [[ $Version -ge 12 ]] then launchctl unload /Library/LaunchDaemons/net.sierra.plist rm -f /Library/LaunchDaemons/net.sierra.plist rm -f /usr/local/bin/sierra.sh exit 0 else rm -rf /Applications/Install\ macOS\ Sierra.app/ # get uid who is running an instance of /System/Library/CoreServices/SystemUIServer.app/Contents/MacOS/SystemUIServer uid=$(ps -ax -o uid,command | awk '/MacOS\/SystemUIServer/ {print $1}' | head -n1) # if no such uid is found, exit [[ -n $uid ]] || exit # execute osascript by user of the uid sudo -u "#$uid" osascript <<-'EOF' tell application "System Events" activate display dialog "macOS Sierra is not allowed on computers at this time." with title "Technology Notice" buttons {"OK"} default button 1 giving up after 30 end tell EOF fi
Good luck,
H
