Sorry, this is a bit long-winded. I was just over at my aunt and uncles place to set up their new iMac and Airport Express and thought while I was there I'd do a bit of maintenance for them. They have a 12'' PB which was still on 10.4.4 so I thought I'd d/l the latest update. Went to software update>check for updates but about half way through checking it would just stop and not do anything. Then I tried to repair permissions to see if that would resolve the issue but as Disk Utility opened it came up with an error message saying it had to quit and to try opening again. No such luck, the same thing kept happening. So instead I thought I'd d/l the update manually from Apple's website. During the install process, when it came to the window to select the destination to install to the HD didn't show up, there was just nothing there so I couldn't progress. I then ran Disk Utility off the install disks, repaired permissions, repaired the disk because it said there was a problem with it and it said the disk was repaired. Went back to install the update again but the issue again hadn't resolved. Disk Utility also continued to have the same error. The computer is running fine, but there's obviously something amiss somewhere. Any help would be greatly appreciated! Thanks.
