Schmitz Apple has released a supplemental update to OS X Mountain Lion 10.8.5 with a couple sleep-related fixes, including a bug that could cause external drives to be ejected after your Mac goes to sleep and a problem that prevented HDMI audio from working after waking from sleep. The supplemental update also fixes an issue that prevented some applications from accessing the FaceTime HD camera on mid-2013 MacBook Air models and a bug with USB Bluetooth adapters. It's available as a direct download from [1]Apple's support Web page (18.7 MB) or via the Mac App Store (19.1 MB). References 1. http://support.apple.com/kb/DL1686 .
