1 ACCEPTED SOLUTION
I took my first crack at adding the deferral functionality to @mm2270's script (I hope you don't mind) and so far it seems to be working ok, although I wouldn't say it is production ready quite yet. I borrowed the deferral logic from @loceee's amazing patchoo script.
I still need to improve the deferral logic a bit. For now the defermode needs to be set to true. The other is the deferral counter reset. Right now, if a user installs any of the available patches, it will reset the counter. So basically it would buy the user another 5 days or whatever threshold you have set to install the remaining updates. I have some ideas on how to address this but wanted to share what I have so far.
Prompt when there are deferrals remaining.
Prompt when there are no deferrals remaining.
Here is the modified script.
#!/bin/bash
## Script Name: Selectable_SoftwareUpdate.sh (v005)
## Script Author: Mike Morales, @mm2270 on JAMFNation
## Last Update: 2016-07-19

## Modified by: Aaron Stovall
## Modification Date: 9/7/2016
##
## Notes: Deferral Logic borrowed from the Patchoo script by Lachlan Stewart (aka. @loceee)
## Defer Variables
datafolder="/Library/Application Support/JAMF/PatchDeferral"
prefs="$datafolder/com.swu.deferral"
# users can defer x update prompts
defermode=true

## Set the installAllAtLogin flag here to 'yes' or leave it blank (equivalent to 'no')
## Function: When the script is run on a Mac that is at the login window, if the flag is set to 'yes',
## it will lock the login window to prevent unintended logins and proceed to install all available updates.
## Once completed, the login window will either be unlocked in the case of no restarts needed,
## or a restart will be done immediately to complete the installations.

## Set the forceEnableUpdates flag below to 'yes' (or any value) to enable it. This option will change the
## checkbox display to show updates as enabled and non-selectable to the user, meaning they will be forced to
## an "on" state for all. Leaving this value blank will retain the original functionality, allowing the end
## user to select the updates they would like to install.

fi@FritzsCorner wow, awesome, thank you for your (and everybody else) work!
Couple things thoughts. one is a different icon came up on the 2nd run through, purely cosmetic, but the first was a jamf icon, the 2nd was the apple software update icon..
the other is, can the install buttons be greyed out unless a package is selected?
@perrycj The closing of cocoaDialog and the negative deferral count I have seen. To prevent closing the window via command+q I don't really have the best solution right now... but I do have a very weak, easy to defeat deterrent that I have tested before. That is to change the keyboard shortcut combination to quit cocoaDialog itself. Like I said... it's weak. :)
This script, with my modifications at least, is not a production worthy solution as of yet. I am making tweaks as I have time.
The deferral method I used was based on what is in patchoo, but there was another script earlier in the thread that uses a different approach.
