I'm subclassing NSTableview so rows will highlight when mouse is over, I'm using mouseEntered: and mouseExited: but they never get called, the only method that gets called is mouseMoved:; I'm not really sure about whats happening, please help.

I think you have to add a trackingRect to the view. Otherwise it doesn't know that you are interested in these events, let alone whether the mouse is inside or outside.

Create your own custom cell and do the tracking in that?
Or maybe this?
tableView:shouldTrackCell:forTableColumn:row:

(Did you look around in the documentation?)
