- Fixes an issue that may cause external drives to be ejected after the computer goes to sleep
- Addresses an issue that may prevent HDMI audio from working after waking from sleep
- Fixes an issue that may prevent certain USB Bluetooth adapters from working
The 10.8.5 update updated a CoreMediaIO plugin that accesses the MBA camera, but didn't bundle the 32-bits version of it.The update for iTunes, version 11.1.1, fixes issues with deleted podcasts and iTunes Extras. iTunes 11.1 was released last month alongside iOS 7
Other (older and newer) versions of the OS do include a universal version (32 and 64 bits), but not 10.8.5.
This means 32-bits apps such as Skype or iMovie cannot load the plugin, making the built-in facetime camera invisible to these them.
Internal releases of Apple software updates to employees typically signal an imminent public release.
