Mac OS X 10.5.7 Update Incorrectly Signed? Had to use Combo Update File

I'm not quite sure what it is about my 1st generation MacBook. But, it has not had much luck with the automated Software Update process. Last December (2008), I noted...

Mac OS X 10.5.6 Update Doesn't Like my MacBook

This time around I had a problem with the Mac OS X 10.5.7 update on the MacBook. After running Software Update, the updater displayed an error that said the update file did not have a correct digital signature. Based on my experience with 10.5.6, I didn't even bother trying to run Software Update a second time. I went straight to the Apple web page for...

Mac OS X 10.5.7 Combo Update

...and downloaded the massive 729MB 10.5.7 combo file (massive compared to the 286MB download through Software Update). The initial update process seems to have run fine using the Combo Update. However, the update process itself is taking forever on my 1st generation MacBook with its 2GHz Core Duo (not Core 2 Duo) processor. After looking at a blue screen with a tiny active hash circle that appears in the center of the lower third of the screen every now and then for about 15 minutes, I forced the MacBook to reboot. It took a minute or two of "thinking" (presumably completing the update) and presented my login screen.

I had exactly the same experience as Todd. I was attempting to upgrade my Macbook Pro with a 2.4 GHz Intel Core 2 Duo. The update program downloaded a version that did not have the correct digital signature. The combo version worked but stalled on the reboot. I did the forced reboot and after several apparent start-ups including the starburst purple Apple screen - the login screen was presented.

I am not sure why Apple can't get the upgrade path to be reliable. I am more impressed that Google found Todd's suggested solution with a very criptic set of keywords. Thanks Google and thanks Todd.

Glen: Thanks for letting me know you found the info useful. I was a little hesitant to post "tech support" type info to O'Relly Media's blog but thought it might be more "findable" than posting to my personal blog. Seems like I was right :-)

Same here, whith a PowerMac G5 2x2 GHz

I have an iMac 2.4GHz and I had the same problem. This was the first time I had a problem with an update, to be honest I got scared...

Same problem here on my 2.5GHz model MBP. Until this update, everything else has worked flawlessly. Had to go get the combo update for this one.
