I'm wondering if there is a way to configure Accessibility settings via Casper or script? It seems like something that should be in Configuration Profiles, as that would be the way to establish a trusted security chain for configuring this. Before I dig in and see if custom settings can control this I wanted to double check and make sure nobody else has already figured this out.
What I want to do is define the list of apps under "Allow the apps below to control your computer" in Mavericks (or the equivalent in previous versions) so that AppleScript, A Better Snap Tool, TextExpander, and other applications that interact via Accessibility can function without requiring an administrator to approve them on every Mac.
