Sorry if I'm doubling up! But I couldn't find the thread I thought I posted yesterday!
I recently created a second account in Mail. Now whenever I open Mail, it asks for permission to use Keychain. I'm pretty sure this happened once before, but I can't remember how I dealt with it. Anybody out there know what to do … it gets to be a drag typing the password each time.
Many thanks to any kind soul who can assist.
