You have to implement an is_inserted function like this one that is
already there for FreeBSD:
static int cdrom_is_inserted(BlockDriverState *bs)
{
return raw_getlength(bs) > 0;
}
The point you're changing is _already_ testing bdrv_is_inserted.
Look at the block starting like this:
#if defined (__FreeBSD__) || defined(__FreeBSD_kernel__)
static int cdrom_open(BlockDriverState *bs, QDict *options, int flags,
Error **errp)
and create a similar one that is #ifdef __APPLE__. Feel free to remove
pieces that you don't know how to do in OS X / CoreFoundation.
