I'm going to give Mac Mail another try. But I can't stand the stamp icon. I'd like to replace it with the iOS icon.
I have the
.icns file but the old "get info" trick where you just paste the icon over the existing one doesn't work. I've also tried "Show Package Contents" on the Mail.app and replacing the ApplicationIcon.icns from the Finder and Terminal under
sudo. No luck.
How can I replace the Mac Mail icon with something a little more consistent with the rest of the OS?
