Apple today pushed out OS X 10.9.1, an update for its Mavericks operating system that addresses multiple issues including a problem with Mail. The update promises improved support for Gmail in OS X Mail, as well as fixes for users with custom Gmail settings. There's also improved reliability of Smart Mailboxes and search, and a fix for a bug that prevented contact groups from working properly in Mail.
Also included in the update is a fix for an issue that prevented VoiceOver from speaking sentences that contain emoji and an issue that stopped iLife and iWork from updating on non-English systems. Apple has also addressed the bug that caused multiple prompts to unlock "local items" keychain and an issue that saw Japanese keyboards retain a previously used language.
OS X 10.9.1 also comes with Safari 7.0.1, which will fix Safari's habit of becoming unresponsive when filling out forms on certain websites (including fedex.com and stub hub), improve credit card autofill compatibility and VoiceOver compatibility with Facebook, and update Shared Links periodically when open in the Safari Sidebar.
You can download OS X 10.9.1 directly from Apple by checking for software updates on your machine. As always, be sure to back up your files before running any updates!
