Blurry/pixelated icons at random in Finder windows

For me, THIS is the solution!

Icon Cache Cleaner, as posted before by Jaba23 ---> http://cl.ly/2o1O3W2j0N0l37411x3c

Cleans up the Icon Cache (the problem, that Apple seems to be too lazy to fix themselves), than resets the Finder.

Thank you, Jaba23! 🙂

My config is: iMac27", 16GB of RAM, System 10.6.8, and (oh, by the way, did I mention that?) lots and lots of 3rd Party Apps... 😝

Thanks to Jaba23 and SeBiG...

For me this is just a very temporary help.

I have been digging around since days and also found a very helpful blog, which doesn't make me feel better because it seems to be no solution, just evidence and hundreds maybe thousands users with the same issue.

How can Apple still do nothing about it???

Here is the blog: http://macbitz.wordpress.com/2010/11/25/the-snow-leopard-pixelated-fuzzy-icon-bu g/

After reading that I decided to write to Apple's feedback and post quotes from many different users with the same problem...

I suggest that all people here should do the same and fill the inbox of Apple's feedback.

Here is the link for feedback to the geniuses who don't care about Apple's reputation!

http://www.apple.com/feedback/macosx.html

I hope you people out there will send them all your facts and rumours so they can start to figure out how to finda cure for the customization, which isn't just for fun...most users need to organize their filesystem by customized icons or for graphic design!

So Apple MUST deffinitely do something about it, and as for my understanding they should give an update for 10.6 as well as for 10.7 users since the problem didn't occur in the good old 10.5 Leopard operating system.

No we won't all buy an iPhone and dance to the flute of their iTunes...

Shame and understanding...that's all they need to get!

Oh, I forgot to mention; this is what you will get after posting your feedback:

The feedback page isn't quite as much help. Instead, go to the Web Sites list in Safari and choose Apple Developer site > ADC - Bug reporting. You don't need to actually be a developer to join. After creating an account, you'll be able to submit a bug report. These reports go directly to the engineers, so they're sure to see it.

Be sure to follow the submission steps. "Please fix this!" is not a report.

I don't see any "Quote" button, so I clicked "Reply". Is that the same?

EDIT: I see it is not. OK, here is the quote manually copied-pasted:

"It only works as advertised when going forward, say from 10.4 to 10.5, or backward over a minor update, like 10.6.1 to 10.6.0. But when going backward over a major revision, the version checker can leave some newer files in place, causing weirdness like this.

I am not convinced by the Apple article you mentioned. I would love to hear an explanation from the author of the article (just wishing) or from you as to how the Frameworks and Library directories manage to sneak out of the archive. After all, they are tucked quite snugly in the /System directory and the /Library directory. Both of those are inside the /Previous Systems when the archive is applied. Do you think the installer looks inside /Previous Systems to see what it can find? If an archive installation is inappropriate over a later reference release, why does the installer not have a check for that? It has checks for dang near anything else.

In summary, I'm saying that article is really truly suspect. Until someone can explain the installer's ability to mix items that are in the /Previous Systems archive with the new directories, I remain skeptical. A Windows installer can get things all bungled up because it doesn't do a proper archive (only renames the Windows directory, leaving the Program Files directory out in the open). In my view, OS X archive is effective for any and all OS versions when it comes to Library and Frameworks directories. What happens to the hidden base UNIX files is another question, but those have no Library or Frameworks.

For me, the problem starts with Safari.

I went in as root, and deleted Safari and replaced it with the same version from my MacBook. That version had been freshly installed on the switch-over to lion, and not updated a zillion times.

And bingo, I got a nice sharp icon.

Here's where it gets weird. I decided to do a "diff" on the 5.1.3 (old, blurry version) and the new (not blurry) version, so I temporarily added the old version back in a different folder. (The difference seems to primarily be in line ending types in the info.plist)

Well, somehow that "older 5.1.3" got launched... and bingo: the blurry icon came back.. even with the "new" safari copy.

But then I noticed this extreme oddity / clue:

I have 588 items in my root-level applications folder.

I view that folder (and all of my folders) as a list. I just now decided to view it as icons, to see how the Safari icon looked. (Fuzzy again.)

But here's the extreme oddity:

Every application icon -after- safari was blurry too! (Only generic folder icons were sharp.)

My icons are arranged by name.

Several hundred icons (from A to Saa) before Safari in the view-by-icon window are sharp and behaving properly.

Every icon after safari (except folders) is rendered from the smaller size: blurry.

Now what does THAT mean?

I found this article helpful in resolving the blurry/pixelated icon problem:

http://support.apple.com/kb/HT1199

Move ~/Library/Caches (the Caches folder in your user library) to the desktop. Log out and log in. The icon problem was solved. Some cache was causing the problem. It would be interesting to know which app was creating the troublemaker cache, but it doesn't really matter. Apps will create a cache when they need one - the process might delay the first launch of an app a bit, but getting rid of the icon problem was worth it.

I didn't have to do the second step of the advice in that support article (delete /Library/Caches -- the system cache).

The fix I posted on Mar 4 2012 seems to be temporary, though it works for a while after the caches are deleted. I also found that removing folders from the Dock that contain alias to various applications cleared up the problem instantly -- too early to tell it the fix is permanent. (Perhaps this indicates a root cause linked to a Dock cache and/or preference?)

Can you elabrate on "removing folders from the Dock that contain alias to various applications"?

Dock folders. For example - as discussed here

http://support.apple.com/kb/HT2474

and here

http://support.apple.com/kb/HT3739

Do you mean the stacks on the right part of the dock? I'll give it a try...

I'm on Snow Leopard 10.6.8. I'm getting the pixilated icons in the Application Switcher. Both Firefox and Logic Pro are both showing up incorrectly.

one more solution

1. Delete all filers from

~/Library/Application Support/Dock/

2. Relaunch dock by typing in terminal "killall dock"

Worked for me on 10.7.3

Doesn't fix blurry application icons in the Applications folder.

I have some improvements to report. I upgraded Logic. That fixed the Logic icon in the Application Switcher. I removed the Firefox link from my dock, launched FF from the Finder, then dragged the resulting icon in the dock up to my preferred location, and that resolved the FF icon display in Application Switcher. These were the only two apps that were giving me problems in the Switcher. Hopefully, the good times will last.
