Mail constantly synchronising (iCloud imap - Mavericks)

I've done last night's update and my constantly syncing problem seems to have gone away. Odd that Apple didn't mention it as a resolved isse in their description of the update.

Same here. I concluded that they didn't mention because they didn't want to admit there had been an issue!😮

It seems that my problem disappeared with this update, too. You're right STav, Apple might not wanted to admit the issue...

Yes I know, I see the Devil everywhere, but I can't believe such a company ignored this kind of issue.

However, they solved the problem.

Unfortunately, I am still having the same issue. I installed the patch yesterday and it seemed to work... but I woke up this morning realizing that this update has not completely fixed the IMAP issues.

People, I recommend you to keep monitoring your IMAP accounts in Mail for at least 24 hours.

On the plus side, Apple released an attempted fix at what seems to be a boneheaded IMAP resynchronization setting in Mail. On the negative side, they released an OS that broke a basic function (email). What does that say about their QA?

Looking at it overall, I see no compelling advantage to upgrading to 10.9. There are no *must-have* features, no great freebies. The upgrade is free, but will cost me hundreds or thousands of dollars in other software upgrades. Say goodbye to PowerPC on Rosetta, for example.

But the new hardware *requires* the newest OS. I'd prefer the option to continue to run Snow Leopard indefinitely. I can run Windows XP or Linux on new Apple hardware but not 10.6. Oh, well....

I like lots of things about Mavericks - esp the new calendar, notes and address book. But releasing with such a serious bug in Mail is wrong and, at least in my experience, unlike Apple. I reported it through bug reporting and had a response from the engineers immediately. So at least they were eager to address it.

This has been true for over two years now since the release

of 10.7. This is nothing new!

Further information. I installed the Mail update as soon as it was available. Initially, I noticed that it seemed to almost resolve the problem. Constant iCloud synchronising was reduced dramatically. But now, as the days go by, I have noticed that the duration of the same synchronising as I reported initially is creeping up again, taking several minutes. I'm not sure this is fully resolved.

And emptying the Mail trash still seems delayed - while the synching is taking place.

Glad I found this thread so now know I'm not the only with this problem. Took me awhile to find out to use activity window and then saw the process problem was syncing with iCloud. Hoping for a fix.

I'm having the exact same issue with my usa.net IMAP account since setting up my new MacBook Pro running Mavericks 10.9.1. Every time I start Mail, any mail on the server disappears and re-downloads. I do not sync to iCloud, so that's not the problem. I'm using the most current version of the operating system, so any "fixes" should have already been incorporation. Initially I had over 20,000 emails on the server, so this took forever! I've moved anything over 2 months old to my local machine and trimmed it down to just under 7000 messages, but it's still painfully slow.

I too have sent feedback to Apple using the link that Patbal posted: http://www.apple.com/feedback/macosx.html

Hello, any update on this? We have the same issue, Mavericks Mail.app is re-downloading ALL IMAP messages every time the app is launched.

I've had no response, and the problem still isn't fixed. I've gotten so that I don't shut down my computer unless I absolutely have to because it will take forever to get my mail back.

I am having the same problem of old gmail messages being continually being re-downloaded constantly. The "bug fixes" and updates have not fixed anything.

I am running 10.9.2 and Mail Version 7.2 (1874).

Does anyone have a solution?
