How can I know the Apple Event Access Groups used by an application?

Question

Apples\' Sandobox is supposed to use Apple Event Access Groups, which allow applications to communicate with each other, as described in the WWDC video \"Session 206 Secure

Answer 1

Apple Events from sandboxed apps is typically done with Apple Script. There is documentation for the entitlement needed here:

To find which app provides access groups is a bit of a hassle and there aren't many available. Use terminal and sdef to find out. this will give you an XML which you can read and look for access-group

eg in Console:

sdef /Applications/Mail.app > mail.sdef.xml
open mail.sdef.xml 

Then you'll see the line
