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 someonesname@domain.com 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.
Thanks to Randy M for the tip

Thank you!
I had troubles with this for quite a while now ..
Wow… cool trick! I was looking for something like this…
Thanks
Thank, thank, thank you!!!!!!!!!!!!!!
Yeehaw!
BIG, GIANT thank you!!!
I’m going to take this opportunity to ask about a somehow related problem.
For some reason the Mail app has stopped using all my Gmail contacts for auto-completion when I’m writing a new email. It only uses “My Contacts” but not the ones that Gmail categorizes as “Other Contacts”. The latter are the ones automatically created every time you share a few emails with a new person.
This used to work but it stopped (maybe it was my fault, I don’t know). Does any one know how can I get this back?
Sorry not the right topic!
Brilliant! This has been bugging me for years!
Thank you, superb tip. been winding me up for so long! Thank you again
Thank you so much!!!!!!!!!
