You're probably better off creating your own similar-looking button.
But before you do, try installing an NSTrackingArea that covers your
button and sending its cell -mouseEntered: and -mouseExited: when the
mouse enters/exits the tracking area. There's no guarantee that this is
how AppKit implements this functionality, but it's worth a shot.
You might also consider filing a bug asking for a standard way to tell
an NSCell that it should draw as if the mouse is over it (rather than
just informing it that the mouse has entered/exited and letting it make
its own decision). As you noticed, "highlighted" does not refer to this
state.
