Apple is preparing a supplemental update for OS X 10.8.5 to address several issues with FaceTime HD cameras on the company's latest MacBook Air models, external drive handling, HDMI audio, and USB Bluetooth adapters, reports 9to5Mac
. The update, which arrives as Build 12F42, has been seeded to Apple employees and should be making its way to a public release in the near future.
The OS X v10.8.5 Supplemental Update is recommended for all users running OS X Mountain Lion v10.8.5. This update:
- Resolves an issue that may prevent certain applications from using the FaceTime HD camera on mid-2013 MacBook Air systems
- 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 FaceTime camera issue in particular has been the subject of a number of complaints, with Skype issuing a notice
acknowledging the issue.
The 10.8.5 update updated a CoreMediaIO plugin that accesses the MBA camera, but didn't bundle the 32-bits version of it.
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.
Skype noted in its post two weeks ago that it would be in touch with Apple about addressing the issue.
