Well, it must be a regional thing then because I also downloaded the 10.8.4 combo update .dmg image and installed it with no error messages. The .dmg disk mounted without issue. If you get the same checksum message then it came off a different server than my image did. And it does not appear to be widespread either. Never assume your issue is happening to everyone.

From which site did you download the Combo, Apple?

I got that error so went back to the Apple Downloads page and downloaded again. Worked the second time without a problem.

Today: The same problem.
I'm downloading via the link at Apple's Downloads page. There is no way I would know what server is holding this copy, if indeed there are separate source copies on mirror servers.
Anyway, I have the previous combo update and the separate updater for 10.8.4 and that will have to do. However, I strongly suspect a lot of people have the bad copy of this file stored for future purposes and won't know it's bad until some time in the future.

If they have the same problem as we did all they need to do is go back to the site and download it again. The second time was a charm for me. Probably problems due to high traffic volume at the server as it took about 10 times as long to download as files that size normally do for me.

Be absoltuely sure that you download from the Apple sites only. One time "unvalid checksum" is very seldom, two times means that that there is another problem!

Happily, Apple has replaced the bad file with a good file. I attempted the download again today (yes, as ever, directly from Apple's Downloads page) and it works. No more error box rubbish. I figured Apple would get around to fixing their problem. But I'm glad I posted this discussion issue so others experiencing the same thing would not feel alone or incompetent, etc. When this happens, it's real and repairable by Apple, not you or me.
Thanks to all who replied and tried to help out! Much obliged.

Still having problems via "Software Update" on Mountain Lion and by downloading the file from apple.com just now. Still has the "invalid checksums" box everytime

Never mind. I got it to work on my own. It's the combo update that is messing up everytime. I went to the Downloads page mentioned above and just downloaded the OSX update ONLY. After that easy download, easy install. Then the other updates in the combo besides OSX updated normally just fine via "Softward Update" on the Mac

I've downloaded the Combo update another time to another computer since the checksum error stopped. Again no problem! I wish I could offer a way to force downloading it from what is apparently STILL the offending server source. There may be some other factor going on, but I have no concept of what it could be. Both computers where I've successfully downloaded it threw the checksum errors for days after the Combo's release.
Again, all I can point at is something outside of our influence as users. At my end, the bad file hasn't shown up again.
Now I get to tackle the beta of Safari 6.1. Not a word from my mouth about it.
