There currently is no Quartz surface in pycairo. It would require a
Quartz user to develop and test the code for the new surface.

It looks like cairo actually supports two Quartz surfaces:
1) 'quartz'
cairo_surface_t *
cairo_quartz_surface_create (CGContextRef    context,
			     int	     width,
			     int	     height,
			     cairo_bool_t    y_grows_down);

CGContextRef may be a problem. If its really a C type (like an int),
then pycairo bindings can be written for this function. But if its some
custom type then there would need to be existing python bindings for it
with a C API that pycairo can use in order to access the CGContextRef.

2) 'nquartz'
cairo_surface_t *
cairo_nquartz_surface_create (cairo_format_t format,
                              unsigned int width,
                              unsigned int height);
This looks more straightforward to create pycairo bindings for.
