Apple has just released OS X 10.8.5 Supplemental Update, which includes a number of bug fixes and iTunes 11.1.1.
Apple had seeded the updates to employees earlier in the week.
The Supplemental Update includes bug fixes for an issue that prevented some apps from using FaceTime HD camera, prevented certain USB Bluetooth adapters from working, caused external drives to be ejected after the computer goes to sleep etc.
The update also includes iTunes 11.1.1, which resolves an issue that may cause iTunes Extra to display incorrectly, fixes a problem with deleted podcasts, and improves stability.
You can download the update via the Updates tab in the Mac App Store or from Apple’s Support page.
Here are the links for the revised versions:
