The insert mode mapping should work so I'm not sure why it's not working
for you. It could be that you didn't do "aunmenu Edit.Copy" as I described
(you would be able to tell if that's the case because you will see the
"Edit" menu flash briefly).
Also, thinking more about it I think advising you to unmap Edit.Copy was
unwise. You could just remap the "Edit.Copy" menu to do the right thing for
you. Just do the following and Cmd-C should work as expected. This makes
the existing mappings work, and after the next MacVim release, Edit.Copy /
Cmd-C will be able to copy from Vim terminals out-of-the-box as well.
Basically, just add these to your vimrc instead of manually mapping <D-c>:
nnoremenu Edit.Copy :<C-Y><Esc>
inoremenu Edit.Copy <C-O>:<C-Y><Esc>
