Why does Mail ask for keychain password and will not send email without it
Problem probably triggered by electing to use digital signature on DocuSign for a pdf document. For whatever reason Apple "Mail" program was stuck in a loop asking for keychain password for user and having only options of "Allow", "Deny", and "Allow Always." User password (and Apple password) did nothing and Mail application was rendered useless.
Does anyone know why Mail asks for Keychain user password? The icon in upper right hand of email message showed seal (stamp) with a checkmark just to right of a locked lock icon. By selecting the seal icon it changes to an "x" I believe indicating the email is not encrypted, but still Mail was not working.
Finally called Apple Support and a very accented voice led me through a couple options, the last one being to change my Mac user password through System Preferences/Users & Groups and unlocking and then selecting "Change Password". This solved the immediate problem but I still do not understand it.
