Excellent! (Not that it fails, but that you have something specific to work on.)
Have you checked to see whether your custom view’s cursorUpdate: is called at all, when it doesn’t work? There’s a difference between not being sent the message, and being sent the message but having your cursor change made irrelevant by the other view changing the cursor afterwards.

If you literally set the tracking area to self.bounds, that is not such a good idea, generally. The bounds might be different at different times. You should really use the option to track the visibleRect automatically.
The other thing you should be looking into:
If the text view uses NSTrackingArea (and my understanding is that it does so, but I don’t know for sure), then it shouldn’t be getting any cursorUpdate: messages *while the cursor is already inside its tracking area*. Therefore, there might be different behavior depending on whether the cursor enters:
— the text field tracking area first, then the custom tracking area deeper inside the text field area, or
— vice versa, or
— both tracking areas simultaneously, because the boundaries are in the same place
Note that the answer is potentially different for each of the 4 edges of the tracking area rect, and for each direction of movement (towards inside/towards outside).
BTW, if the text field is changing the cursor on mouseMoved: events, which is possible, then your attempts to control the cursor with cursorUpdate: seem doomed to failure.
