My company recently updated their Keynote template. I used Jamf Composer to create a snapshot package where I used the Keynote app to manually save the theme as a template. I saved it as a DMG, and applied it to a policy that Fills existing users. It does exactly what I expect, placing the .kth file in the user Keynote directory (~/Library/Containers/com.apple.iWork.Keynote/Data/Library/Application Support/User Templates). However, upon opening Keynote.app, the theme does not appear in the Theme Chooser.
The final strange detail is that on the same computer I've been testing the policy on, if I create a new user before running the policy that has never opened Keynote before, the template does appear in the Theme Chooser on that second account, but will still not appear in Keynote on the first account.
I'm very new to this so please don't hesitate to suggest that I've made a mistake that seems dumb or obvious to you, it's entirely possible. I'll take any and all advice and appreciate it!
