I suspect the issue is that NSButton does not have built-in semantics for control size. In fact, none of the cells in question are documented to respond to -setControlSize is the way you are seeing, but apparently some do. If you consider that a button of any control size can actually be of any size, how would the cell know how to resize itself, other than to just change its font? And if it has an image, how would that work? Because you can't guarantee KVO compliance for any API object that doesn't explicitly state so the only way to reliably know what is happening is to use your own NSButtonCell subclass (better than a symbolic breakpoint). You might actually find that you will need to handle resizing yourself anyway so your work won't go to waste. If setControlSize is really not being called on the cell, then it is probably being handled like any regular view, and then you will probably need to specify the min/max sizes.
