ARD Login Script errors

Question

ARD Login Script errors

I've been using this as a unix command to login a lab of computers for several years

osascript -e 'tell application "SecurityAgent" to activate'; \

osascript -e 'tell application "Bluetooth Setup Assistant" to quit'; \

osascript -e 'tell application "System Events" to keystroke "student"'; \

osascript -e 'tell application "System Events" to keystroke return'

osascript -e 'tell application "System Events" to delay 0.9'; \

osascript -e 'tell application "System Events" to keystroke "learn"'; \

osascript -e 'tell application "System Events" to delay 0.9'; \

osascript -e 'tell application "System Events" to keystroke return'

and randomly get this error message back;

osascript[58392:3633525] CFPasteboardRef CFPasteboardCreate(CFAllocatorRef, CFStringRef) : failed to create global data (repeated 10+ times or more)

the login works, so just curious to know what might be causing this error.

This same question was asked a few years ago in this discussion https://discussions.apple.com/thread/7382301

With this as one suggested solution:

If that does not work, for the account your using to remote into the computer.

Log into the client. User Directory Utility to enable root

login to the computer as root

open system preferences Security & Privacy

click on privacy tab

click on accessablity

check SystemUIServer

When I follow these instructions there is no SystemUIServer to check.

iMac, 10.8.x - 10.11.x

See if invoking the script with sudo -u username {command}, where username is the user you want to run the command as. If you don't know the user, then sudo -u $(ls -l /dev/console | awk '{print $3}') {command} can get that for you.

Well, I am using this in a Unix command from within Apple Remote Desktop ran as root, the iMac is at the login window. So not real sure where I would put the sudo information. I think ARD does that when send as root is checked.

The root user is a user. The sudo commands shown switch to a different user; to the specified user, or to the current GUI console user.

sudo -u username {command}

sudo -u $(ls -l /dev/console | awk '{print $3}') {command}

In this case, {command} is the name of the shell script containing those osascript commands. If the script is in the file /Users/Foobar/myscript, then the commands would be:

sudo -u username /Users/Foobar/myscript

sudo -u $(ls -l /dev/console | awk '{print $3}') /Users/Foobar/myscript

I feel like we are not on the same page here. I am using a Unix command from the Apple Remote Desktop Admin app and sending this as root to machines that are at the login window. Not a script saved locally on the machine, which I suppose I could try. But this worked without any feedback or errors up to Os 10.10.x, then started showing the described feedback or error when the machines were upgraded to 10.11.x. I haven't notice if I get the same results on 10.12 or 10.13 machines, but will check tomorrow.

Fortunately, the login process still works on the 10.11.x machines. I was just curious about where or why I was now seeing the error above.

Then send each command with the specified sudo, and see if that works?

I understand that this used to work for you, and that macOS has changed, and I know that security around the GUI has gotten upgraded for various reasons — processes running under different users and trying to access the GUI is not goodness from the perspective of security, unfortunately.
