Okay, so maybe a bug fix update isn’t the most exciting thing to show up in the Mac App Store, but if you’re a Gmail user running Mavericks, this is probably the update you’ve been waiting for. Apple has just released Mail Update for Mavericks 1.0 (Free). If you’re running Apple’s latest OS and use Google’s email service in the built-in Mail app, we suggest downloading it right away.
From the start, we’ve heard complaints from Gmail users suffering all sorts of issues, including duplicate messages and a delay in receiving their email. Hopefully, this should fix all of that. The 32.5MB bug patch is pretty small, and no restart is required. For more information, check out this Apple Support page.
