Many times before I have wanted to copy the email address when I get a mail from someone, but when I copy the address in Mail you get the Persons name and the email address something like Fred Bloggs <Fbloggs@myemail.com>.
I was listening to the Maccast podcasts and I heard a tip that will turn this off so you get just the email address.
To activate this go into terminal and type:
defaults write com.apple.mail AddressesIncludeNameOnPasteboard -bool NO
If you do want this "feature" back, then you run the command again but change the NO for YES.
I am always interested in feedback so please feel free to add any comments, or you can mail me here. If you would like to submit a quick tip with full credit and links back to your site then also feel free to contact me.
