I have a Gmail account that is configured on three different Macs, let's call them Home, Work, and MacBook. Home and MacBook are on iCloud, Work is not, and MacBook is the one experiencing the issue.
No matter what I seem to do, Apple Mail on the MacBook, for only this Gmail account, displays no messages in any folder, and indicates two unread messages in the inbox. Home and Work display the same account correctly, with an accurate reflection of the inbox and messages contained in other folders.
Things I have tried:
- Disable account, quit, remove
~/Library/Mail/V2/IMAPfirstname.lastname@example.org, then restart
- Removed the keychain items for the account from iCloud, remove folder above
Each time, the account comes back with two unread messages out of zero. The Account Info screen shows accurate numbers for everything except the "Sent Mail" folder (though nothing in any folder displays). In experimenting with enabling and disabling IMAP for labels within Gmail, I have seen the item for the "Sent Mail" folder in Account Info display with the correct number of messages, but a title of
"Sent Mail" does not exist. Very odd. Sorry I don't have a screenshot of that.
