I haven't installed/played with it yet.
Given that my search for xÌ… has been resolved, there's no rush for me to do so.
But the option+shift+A is the combining macron route there too.

EDIT: I notice that here and earlier, once submitted, the xÌ… renders with the macron slightly offset to the right. It doesn't do so in the composition of the post or its editing; and in my documents it renders properly.
