I bought leopard today, and once i did an archive and install, all my apps work fine. except, i cant do a software update. to upgrade to 10.5.2 I keep getting the message softwareupdate can't connect to the internet, make sure you are connected to the internet then try again. i run network diagnostics, set the location to automatic,connect via airport, it recognises my hub, type in my password, then i get the message. network change detected your network configuration has changed, click ok to proceed to the next step. then i just go back to the screen asking my to type in my password. is there any resolve to this. i cann connect to the internet fine though i never had these problems with tiger.
