Stop Pasting Full Names When Copying an Email Address in Mac OS X Mail
Ever noticed that when you copy an email address from OS X Mail app and paste it elsewhere that you get the addressees full name as well as their email address? Try it yourself by right-clicking on someones email address like firstname.lastname@example.org and copy it, then paste it elsewhere and it will show up as “Someones Name
To resolve this copy/paste annoyance, launch Terminal and paste this line into the command line:
defaults write com.apple.mail AddressesIncludeNameOnPasteboard -bool false
Relaunch Mail app for changes to take effect, then try to copy and paste an address. Only the email address should go to the clipboard now.
