I've installed the latest version of Skype on my Mac and though all my softwares are up-to-date, Skype keeps on crashing my system.
You can try one of the following.
First close Skype:
- Go to User/Library/Preferences, delete the =.com.skype.skype.plist file
- Go to User/Library/Application Support/Skype, delete the shared.xml file
- Delete the User/Library/Application Support/Skype folder
Launch Skype and the deleted items will be automatically created.
