Hi,

I'm setting up a Software Update Server. I noticed that some updates appears twice in the list. Can someone please explain to me what this difference is between the following updates?

Safari 3.2.1 (26.6MB)
Product ID: 061-5803

Safari 3.2.1 (39.9MB)
Product ID: zzz061-5804

What I'm interested in is the zzz in front of the Product ID. I noticed this prefix many times.

Thanks in advance!

Mac OS X (10.5.6)

    Interesting question.

    After looking at my server, and then looking at the different packages and the descriptions in the Software Update, I can tell it is not an architecture indicator (Intel vs PPC) or a combined vs a point update indicator.

    Since other updates are posted with 1,2 or 3 "z"s, I am going to guess it has something to do with controlling when in the process of a software update the particular update gets run. That is, if your machine needs several updates, the prefix might control which one would have to go last. All the OS updates have a "zzz" prefix. Why two different packages for Safari? I don't know, but it might depend on OS version or updates already run.

    That's my guess; I'd still like to hear from someone who really knows.
