I’ve just noticed that some(?) settings on Macs seem to be involatile. My resident actions to set them to desired values have been failing for a couple months(?). When I manually run my change actions, the value in fact does not change.
parameter "theSetting" = "_BESClient_Report_MinimumInterval"
parameter "theInteger" = "60"
setting "{parameter "theSetting"}"="{parameter "theInteger"}" on "{parameter "action issue date" of action}" for clientPossibly because of the Effective Date?
If you have something like a policy action where you want to reapply your settings, that action has the Effective Date set as “the time the action was taken”.
If a later action changes the values, your old action will not set them back to the original values because the first action has an older “effective time” for the value.
If you want a policy action to keep reapplying the values in the future, that’s the rare case where you may want to change on "{parameter "action issue date" of action}" to on "{now}"
Figures that I’d have been sitting neck-deep in a rare edge case for … years now. 
Tagging back to say… this worked! Thank you!
