Then open ~/Library/Application Support * and drag the Skype folder to the trash.Open your Applications folder and drag your copy of Skype to the trash.To completely uninstall, and then reinstall Skype for Mac:

Remove all of the current skype files from your computer. The new version of Skype doesn’t work and I had accepted that fact until out of desperation I discovered that with some simple modications it is possible to run an older version of Skype on your older Mac. I have a Powerbook G4, running OSX 10.5.8 on on PowerPC processor. The only problem is that Skype is no longer working on Macs with anything other than OS X 10.6 – 10.8. If, like me, you are not in a position to afford a newer Mac and are quite happy with the one you have.

Running on the old powerful version 2.8 that now is back to run on any MAC any OS starting from 10.4 and up Skype running on a Powerbook G4 PPC with OSX 10.5.8

Skype works fine on older Macs, powerbooks and power pc g3 g4 g5 – Tiger Os Leopard and even INTEL.
