Hi - I installed Maverick latest patch (10.9.2) a couple of weeks ago and it did not resolve my issues with Apple Mac Mail. The email account keeps caching emails. Also, mail seems to start and never end some kind of update on the attachment file names. I get multiple "Updating Attachment names for messages". -- see attachment in the activity monitor. In fact, I am experiencing the same issues as stated here: http://www.wired.com/2014/02/apple-mail-retrieval-bug/ (note: It seems that the first article is not longer posted) http://www.wired.com/2014/02/apple-mail-retrieval-bug-2/ I never had the problem with mountain lion; and I am having the issue in multiple Macs with Maverick. Anyone is having the same issues? Any resolution?
