Apple Seeds OS X 10.9.1 Build 13B40 to Developers
Last week’s build included several fixes for Gmail in OS X Mail, along with improvements to the Smart Mailbox functionality. It also included bug fixes for emojis when used with VoiceOver, and included an update to the Shared Links tab when the Safari Sidebar is open. Build 13B40 includes the same fixes.
Registered developers can download the update through the software update tool in the Mac App Store.
