Last night, I installed Leopard on my Core Duo Macbook, a clean install (wipe the drive and install). No problem. I then installed iLife 06. Then I started downloading updates via Software Update.
When I tried to download several updates at once, the download eventually hung. So I went back and installed the ones that did download completely one at a time. Then I downloaded some additional updates one at a time and installed them.
But I've got 4 updates (iWeb, Garage Band, iPhoto, and the big OS X 10.5.2 update) for which the download froze up in the middle of downloading. When I look at them in Software Update, it shows "Partially downloaded: xx%" for each of them. But it WILL NOT continue downloading them. When I select them individually to install, the download progress window appears and says "Downloading [whatever] update..." but the line with the amount downloaded and the download rate does not appear, and the progress bar is completely empty. So it just won't finish downloading those updates.
I've tried downloading the .dmg file for the OS X update through Safari, and it gets to about 25 MB downloaded and hangs up forever, too.
I've been running Tiger and installing updates for like a year and a half with no problems. I've tried this on wireless and I've tried it wired. I know my network connection is active - I can surf on the Mac or my PC while I'm updating. I wouldn't swear that the connection didn't glitch momentarily while I was downloading the updates, but that shouldn't break things this completely.
I don't have any idea what else to try - I've rebooted, etc. If I knew where the temporary partial downloads were stored, I'd go delete them and try again, but I can't find them. Any ideas? Worst case, I guess I'll just have to reinstall and try again, but hopefully it won't come to that.
