I haven't installed it either, not sure what it does exactly, so I guess I'll hold off until more people know about it...I received the same update, and I did a quick Google search before installing it..
There is no mention of it on Google, nor on the Apple website, so I will hold off till others try it first.
I don't have a SSD in my MacBook. It just popped up on my updates.I am wondering if it is an update to correct the super slow shutdown in Lion...?
My SSD equipped MB Pro has been taking @ 45-60 seconds to shutdown since I upgraded to Lion, whereas it used to shutdown within 4-5 seconds when I was on SL.

This update addresses an issue where certain new APIs for file access are not present on some systems.
So i think this is a fast security update. Package contents (click to enlarge):<groups>
Exactly. I noticed that on the bottom of the updates page there's no kb website or whatever you call it like there usually is when Apple sends out an "official" update. That's kind of what threw me off about this update.And strange that there is nothing mentioned on the Apple website..... Sounds very strange to me
This makes sense. It only showed up on a newly built Mac with 10.7.4 DVD.I got this supplemental update in Software Update only on one of my Macs, the one on which I had recently reinstalled OS X 10.7.4 from the Mac App Store.
So, it might be that this update is needed only for fresh 10.7.4 installations, while it isn't on systems upgraded from earlier Lion versions (e.g., from 10.7.3).
This is confirmed also by the fact that, when browsing through Time Machine backups, the relevant files (i.e., /System/Library/CoreServices/ScopedBookmarkAgent and /System/Library/LaunchAgents/com.apple.scopedbookmarkagent.xpc.plist) weren't present before the supplemental update on my freshly reinstalled Mac; while they were already present (and thus with no supplemental update offered) on the other ones, which had been updated (with delta updaters) from 10.7.3 via Software Update.
So, it looks like Apple forgot to include those two files in the Mac App Store Lion 10.7.4 installer (and maybe also in the 10.7.4 combo updaters?).
At least, one possible explanation (and the package is signed by Apple, so it should certainly be authentic)...
Well I've had mine updated to 10.7.4 since the release date this version. So I'm still not sure why its showing up on select macs and not all of them...This makes sense. It only showed up on a newly built Mac with 10.7.4 DVD.
This update has not showed up on my other Macs.
