Hi there, Since upgrading to Mavericks I am now not able to create any new Rules in Mail. I highlight an email, Preferences/ Rules and create a Rule to send any future emails from that particular address to a Mailbox which I have created. The usual window appears asking me if I want to apply my rules to messages in selected mailboxes, I click 'Apply' and nothing happens - the selected email does not transfer to the selected Mailbox. Does anyone have any thoughts, or is this something that might be corrected when 10.9.1 appears? Other than that irritation, Mavericks is working very well for me. I suppose I am one of the lucky ones .... Any sound advice will be gratefully received with thanks! voicebox.
