automating "Reset Advertising Identifier" is it possible?
Example #1 - via Googling

Googling I found this Reddit thread titled: I want to write auto reset script for Advertising Identifier.

The script from one of the replies in that thread is below. 

NOTE: I did not test this, am merely sharing it as something that may help steer you in the right direction to ultimately getting a workable solution for you problem.


  FYI, I created a small script for this. It's not perfect, and doesn't
  reliably run in the background, but in case it helps anyone:

-- TODO: make this run reliably in the background...
set isRunning to false
if application "System Preferences" is running then set isRunning to true

tell application "System Preferences"
  activate
  reveal anchor "Privacy" of pane "com.apple.preference.security"
end tell

tell application "System Events" to tell process "System Preferences"
  delay 0.3
  click button "Reset Advertising Identifier" of group 1 of tab group 1 of window "Security &amp; Privacy"
  delay 0.2
  click button "Reset identifier" of sheet 1 of window "Security &amp; Privacy"
end tell

if isRunning is false then
  quit application "System Preferences"
end if



Script appears to be AppleScript.

Example #2 - I made using Automator

This is the first script I've ever done using Automator (be kind). I used the record button and clicked through the steps to construct a Workflow. 

Automator Workflow



Once I made he workflow I copy/pasted it into ScriptEditor.

Copy/Paste from Automator &rarr; ScriptEditor



In ScriptEditor I could click the play button to run the script to debug it and see that it was working correctly.

One I had it working reasonably well, I put it into a Bash shell script so that I could run it standalone from a terminal.

And here's the finished Bash script with the osascript embedded within:

$ cat reset_advertisement_id.sh
#!/bin/bash

osascript &lt;&lt;HERE

on doWithTimeout(uiScript, timeoutSeconds)
    set endDate to (current date) + timeoutSeconds
    repeat
        try
            run script "tell application \"System Events\"
" &amp; uiScript &amp; "
end tell"
            exit repeat
        on error errorMessage
            if ((current date) &gt; endDate) then
                error "Can not " &amp; uiScript
            end if
        end try
    end repeat
end doWithTimeout
