Following a Mail update for Mavericks in November, Apple today released OS X 10.9.1, an update that contains stability and compatibility enhancements for Mac computers.

The update also includes improved support for Gmail in OS X Mail, improved the reliability of Smart Mailboxes, and fixed an issue that prevented VoiceOver from speaking sentences that contained an emoji, among other updates.

• Improved support for Gmail in OS X Mail, and fixes for users with custom Gmail settings
• Improves the reliability of Smart Mailboxes and search in Mail
• Fixes an issue that prevented contact groups from working properly in Mail
• Resolves an issue that prevented VoiceOver from speaking sentences that contain emoji
• Updates Shared Links periodically when open in the Safari Sidebar

The update can be downloaded from the Mac App Store and requires a restart.

Apple has also released a separate version of OS X 10.9.1 designed for late-2013 13-inch and 15-inch Retina MacBook Pros, which, alongside all of the updates already mentioned, contains additional system-specific enhancements.
