I was chasing down another issue (slow "Save As") and thought these two issues may have been related (with QuickLook being the common broken link). Unfortunately, my "Save As" dialog is still miserably slow on the initial load; but IconServicesAgent hasn't gone above 30MB and he rarely makes an appearance in the Console!

Some of these steps may not be necessary, but here are all of the steps I took that inadverdently put IconServicesAgent back in its place. Note: all commands are a single-line, if they appear to be multiple that's just the forum formatting.

1. Check for any QuickLooks related .plist files. In a terminal: mdfind com.apple.quicklook. -name .plist

2. I only had files at the system level (specifically within /System/Library/LaunchAgents/). If you have others, modify the directions below to take that into account (re-introducing plist files from the system level back up to the user).

3. Make some temporary directories to store these plist files, just in case: mkdir ~/tmp-quicklook

There was [a tweet][tweetSoto] a couple of days ago that resulted in a discussion/question about what it wrong with the usage of removedOnCompletion = NO in the [SparkRecordingCircle code][code] for that [Subjective-C post][post].

We all kept saying that the explanation doesn't fit in a tweet, so here is my rough explanation about the issues.

But, let me first say that I think that the Subjective-C articles are reallt cool and useful to learn from. This is trying to reason about the general usage of removedOnCompletion = NO, using that code as an example, since that was what was discussed on twitter.

---

The root problem, as [Nacho Soto pointed out][rootProblem], is that removedOnCompletion = NO in combination with fillMode = kCAFillModeForwards is almost always used when you are not updating the model layer. This means that after the animation has finished, what you see on screen is not reflected in the property of the layer. The biggest issue that this can cause is that all the
