My girlfriend Svetlana has MacBook Air and just recently her skype Video calls stopped working once again after Mac OS X offered her to apply some update. Her notebook as of time of writting this post is running Mac OS X version 10.8.6. About 1 month and a halfago she was facing same Skype No VIdeo on Mac BookAri issues for how I fixed her No Video Skype issues back then check here. Initially I thought again the problem will be identical and to test if Web Camera hardware is detected on a hardware level by OS, I tried to check if it is displaying videoi FaceTime application. Last time there was no Video in Skype on her Mac Book Air I remember clearly camera was detected on OS level and displaying well in Facetime, however this time even in facetime I couldn't see a capture of myself … As obviously problem was not in Skype Mac OS previous time fix of substituting AppleCamera.plugin with older version would not fix it. After some evaluation on problem and reading large number of posts on Apple support forums, I've came to the conclusion that it is possible the whole issues are faced by improper permissions applied by latest applied Mac OS update. In such cases people were recommending to Repair Mac OS Standard OS Files Permissions using an OS embedded tool called Disk Utility.
Disk Utility is an application that's built into OS X that can perform lots of useful and even scary actions.Sysadmins and advanced users seem to find frequent need of this handy tool but those newer to the Mac OS it is better to only use it after reading the docs and well realizing what exactly doing.
To Find / Open Disk Utility on Mac OS;
Launch Applications folder -> Utilities (folder), click the name of your startup disk, and select Repair Disk Permissions.
As I can understand from other ports reverting Mac OS File permissions to their default can solve a number of strange issues with Mac OS.
After repairing Mac OS X basis OS file permissions and testing in FaceTime and Skype, Camera god detected and Video was working fine 🙂
Hope this little article helps someone to fix same issues, if so please drop a thank you comment 😉
