I would like to use bindings to enable/disable buttons based on the on/off state of other buttons.

You really shouldn't do that.

Instead your On/Off button should alter the state of some model data. Then you bind the enabled property of your second button to that model property through a controller.

The model controller might of course be the File's Owner. In that case you'll need an outlet to the first button (button1) and a variable to hold the state:

IBOutlet NSButton *button1;
BOOL button1State;

Now bind both, button1's 'value' binding and button2's 'enabled' binding, to <controller>.selection.button1State. Done.
