The complaints of Gmail users using Mail 7.0 in OS X Mavericks have been well documented, and it looks like Apple has finally come out with a fix. The company on Thursday released Mail Update for Mavericks 1.0.
According to the support document, the fix addresses problems with Gmail, such as issues with deleting, moving, and archiving messages for those with "custom Gmail settings" and inaccurate unread counts. Apple says the update also, "Includes additional fixes that improve the compatibility and stability of Mail."
After installing the update, Mail will still report being version 7.0 though it will have a new build number (1822 instead of 1816). Before you install the update, Apple advises you to back up your Mac. You can get the update by choosing Software Update from the Apple menu, or by launching the App Store app on your Mac, and then check for updates. The updater is also available manually from Apple's support downloads site. (Some users, who had the development Golden Master release of Mavericks installed, are reporting problems seeing the update.)
Unless, of course, you've already moved on from Mail to another email client. You can just sit back, relax, and check you mail, while the rest of us install the Mail update.
