I was just checking whether I needed to manually unbind any bindings that I make manually. Looks like I don’t, according to the fragment below from the NSKeyValueBinding.header. Binding obviously involves observation and the header note makes it explicit that removing observers is recommended. I think the one exception is self observation. I think under GC observers may have been removed automatically - cannot quite recall. Header note: Bindings are considered to be a property of the object which is bound (the object the following two methods are sent to) and all information related to bindings should be retained by the object; all standard bindings on AppKit objects (views, cells, table columns, controllers) unbind their bindings automatically when they are released, but if you create key-value bindings for other kind of objects, you need to make sure that you remove those bindings when you release them (observed objects don't retain their observers, so controllers/model objects might continue referencing and messaging the objects that was bound to them).
