I want to use Mac CMD+C for copy and CMD+V for paste in Spacemacs but I think it redefined CMD to Meta. How do I change this mapping behavior?
I found mac-key-mode but that package seems old and I don't know how to add it to Spacemacs.

Spacemacs has a "layer" called "osx" that should do everything you want.
osx in the
dotspacemacs-configuration-layers section and you should be all set.
If instead you just want to have some particular os x keybindings, you might find the ones below helpful:
