I've been doing some research on this for a while, but I have found nothing of value. I have a beta build of Leopard installed on my Mac right now, and I want to update that to 10.5.1. Is this possible? I have the update downloaded and extracted, but it doesn't want to install. I have got it to run without giving me and errors, but it gets to the 'configuring install' phase and just hangs. Any help would be greatly appreciated.
