I just got a new Power Mac and installed all the application updates after booting. I also noticed the update for OS X 10.4.1 and tried installing it. After downloading it and attempting to install it, it said it couldn't install it because the downloaded package was invalid (or something to that effect). I went to Apple->About this Mac and saw that it shows the OS version as 10.4.1. So what exactly happened??? Is there any other way I can verify whether things went well? (I no longer see the 10.4.1 update in the list) Thanks!
