Hi all, I have many accounts configured on Mail on my Mac (OS X 10.10). I have a signature set up for all of the accounts under 'All Signatures'. But it never seems to show up whenever I compose a new email? If I click where it says 'Signatures: None', it comes up with 'None' and 'Edit Signatures'? How come my signature under 'All Signatures' doesn't show up? Please help. Thank you!
