When attempting to use NSPopupButton and bindings to

I don't believe specifically for your case (ie, an NSPopUpButton),
but this list's archives contain various (attempts at) textual
explanations.
I keep getting "cannot perform operation without a managed object
context"
This would seem to imply that I should be using CoreData.
In Interface Builder, inspect the Attributes of your array
controller. You'll see a mode control that lets you specify whether to
use a Class or an Entity. You most likely have Entity selected (which
requires a MOC, as the error says). Select "Class" instead.
Is CoreData really the way to go when trying to do much more with
bindings ?
No. The two interoperate very well by design but are not mutually
inclusive.
