Why isn’t Skype for Mac OS X starting?
Another common issue is with the default text-to-speech setting on Mac OS X. To change the default text-to-speech setting:
- In the menu bar, go to the Apple icon > System Preferences... The System Preferences window opens.
- In the System section, click Speech. The Speech pane opens.
- Go to Text to Speech and in the System Voice drop-down, select anything other than the current selection.
- Try to start Skype again.
