[question/help] Reskin problem on mac (green skin in wow)

[Forgiving]

ive looked around and followed a few guides on model editing on a mac.
Im trying to do a simple reskin and so far ive been able to do everything except when i drop my new patch into the data folder nothing changes in wow.
If im editing a Water Elemental, do i need to delete the original skin, convert the whole extracted MPQ back into common.MPQ and delete the original common.MPQ? Im not sure whats wrong
I named the reskin patch-enUS-3.MPQ so i think i have the correct name.
Is there anyone that has model edited on a mac could write a short guide to help? Or if anyone has any suggestions please post them.
+reps if you can help
EDIT: Well now my water elemental is pure green in game...do i have to delete the original texture and convert back to mpq?

[Forgiving]

anyone have any idea how to fix this?
