Addon Version
10.1.3-classic

World of Warcraft Version
Classic Era

I have following macro:
#showtooltip
/cast [mod:cmd] Banish; Banish(Rank 1)

Putting this macro on a default action bar eg. shift+1, it works like this:
shift+1 -> Banish Rank 1
shift+cmd-1 -> Banish Max Rank

In Dominos this is not working. Pressing shift+cmd-1 casts the spell bound to cmd+1.

This is a unique mac (cmd/meta) problem, as shift+alt is working in default and Dominos.
