How to get Skype working for Mac OSX
The issue is typical Microsoft – they test it for PCs and don’t bother with Apple’s hence the video doesn’t work when making a call.
The solution is to download an earlier version of the software that works: 18.104.22.16846

It works! Try it out then feel free to write abusive complaint emails to Microsoft at email@example.com
