Mac G3 or G4 ?
Because you are running Mac OS X 10.4.11, you will have to use the 2.8 version of Skype found here: You can probably use v2.8.x of Skype for your Mac which is found at: Support (link at top of page) > More > Earlier Versions of Skype
Version 5.x requires Mac OS X 10.5.8+
I dowloaded the Skyp 2.8.0 for OS 10.4.10, BUT IT WOULD NOT INSTALL. the message is " You have no previlages to install some of the items" what is this? I have installed other apps using my master password???
I was advised to delete Skype 2.0.0 and all it's files and then try to install ver 2.8. I amafraid that if I delete it and 2.8 does not install, I WILL HAVE NO 2.0.0 version too as it is NOT AVAILABLE ANYMORE.
Zip your actual 2.0.0 version *before* trying to install 2.8.
