Here's a new one that I haven't seen before. I just got my new 1ghz TiBook in the mail today. It came with a fresh install of 10.5, with none of the updates run. I deleted the existing users and ran set-up assistant(a process I've done many times on used Macs), then used Migration Assistant to migrate the user account from my other TiBook. I double checked, and indeed it is an admin account. When I try to download the 10.5.8 combo update, I get the below error message. I do have a flash drive that has the 10.5.8 combo on it(along with several other things that software utility usually runs) but inadvertently left my keychain of flash drives at work today. I'll try tomorrow and see if I can run it from the USB drive. In the meantime, though, has anyone else ever seen this error message?
