[MAC Development] ASIO driver

I know that on Mac OS X CoreAudio is THE protocol to use for Audio IO device drivers.
However, the ASIO SDK seems to support Mac, even though MAC OS 8/9 isnt supported anymore.

Basically I want to know wether Cubase MAC implements the ASIO host interface and the coreaudio2asio is a wrapper to bridge asio to MACs coreaudio system.

If so, does Cubase MAC support OTHER ASIO drivers, developed with the ASIO SDK on Mac?
