I have a very annoying problem with Apple Mail. I have used the app ever since 10.2, until now, which I have for the time being changed over to Unibox, which is very nice, although quite slow.
Anyway. My grief is this, the unread count is very slow to go down. F.ex. now I have 0 unread emails, but the icon on the dock says there are 75 unread.
This hasn't been a problem, until 10.9.1 or thereabout. I have gone in and ran vacuum on the email database, but to no avail.
I could of course delete all accounts, all email, but I can't see that fixing the problem, I have also a more than a few GigaBytes of emails, and some accounts that are no longer active, though the emails are still in the app.
Any help is appreciated. I know this might seem a minor, but having unread count on the icon does bother me and in the folder view. I only want to see the unread count, when there are unread emails. Right clicking on the account/folder and choose mark all as read does nothing, and rightfully it is often greyed out.
And lets not forget that an account might have new email, that is not showing up inside the unified inbox.
