Today I reformatted my 15 PowerBook G4 (1.5ghz) and put a copy of Tiger(10.4) on it. I am having 2 problems now. Problem #1 Software Update I first went to Software Update and wanted to bring my 10.4 up to 10.4.11. It found several updates, as you can see in the picture attached. It ran through the updates, but when it would try to install the download, I would get this error (pic) http://i11.photobucket.com/albums/a160/ChiLLot/Picture1-1.png Now after some research, Apples site said I should deselect all of the updates except the combo update, and then I should be fine. That is not the case, software update will not work. I downloaded just the file from Apple, and I still get the same error. http://docs.info.apple.com/article.html?artnum=303134 Problem #2 Wireless Network When I selesct my wireless network from the Airport pulldown, it asks me for my WPA password. After I type in the password, I get this error. The wireless network "XXXXXXX" does not support the requested encryption method. Google was no help, been looking for a simple answers to these guys. If anyone can help out, Id really appreciate it. Thanks!
