Where have my MS icons gone in Yosemite?

Same problem here. MSFT aware of issue. I have latest Yosemite and Office on an older iMac, no problem. On a new Macbook and new downloaded Office, blank icons.

Did exactly that. Worked like a charm!

Deleting all of you caches is not needed and just takes time rebuilding them, again. This just rebuilds the icon store -- just what's needed.

All you need is build into Yosemite. You don't need to download any programs (that can be a safety threat).

Thank you. I recommend this solution to the problem.

Thank you

Still the same issue after trying all above mentioned fixes. Nothing solved the issue in my case. Some icons are displayed correctly, some not. It varies between the several view-modes in Finder. Almost all VLC-Player, Safari Link icons and MS Office Word and Power Point icons are missing in list- and column view in the Finder. When I drag and drop them on the Desktop, the icons are displayed correctly, most of them... chaos...

My resolution was to uninstall Office create a new user account and reinstall Office. My opinion is there is definitely an icon problem with Office related to Office, Yosemite or both. Uninstalling/Reinstalling Office on the user account where it didn't work originally, didn't work.

First they want to hide all of my file extensions, and now they are hiding all of the icons in the thumbnails? What in the world is going on here.

I will have to back track a few pages to find a solution, nice.

I used Onyx to clear icon caches which worked for me.

I tried Onyx as well, but it had no success...

Thanks! Same issue and solved through terminal. Previous attempt through finder didn't work. Couldn't empty trash after deleting "~/caches/com.apple.iconservices.store" and would write a new file immediately after deletion attempt.

Worked perfectly through terminal, after all apps previously closed.

I add the same issue as you did. Check the "The Dark Knight" solution through the terminal... It worked perfectly.

After trying "The Dark Knight" solution the Microsoft Word icons are back in list and column view. Unfortunately this is not true for the VLC (extension .flv), Safari Webloc link icons and PowerPoint icons. They are (or most of them) still not showing up in column and list view in the Finder :-(

The issue persists since I did a clean install of Yosemite. After clean install of 10.10.1 I copied only my essential user files manually from my Mavericks-TimeMachine Backup to the cleanly installed Yosemite-System. I copied the content, not the folders inside the user folder themselves.

This is what I tried so far:

- Safe Boot

- Deleting all Cashes manually several times in:

~/Library/Cashes

~/Library/Saved Application State

/Library/Cashes

/System/Cashes

- Onxy automated Tasks including deleting all .DS_Store, restoring Folder content view and all the rest...

- reassigning the affected files to the corresponding Application in Finder Info window to "open with" and "change for all"

- "The Dark Knight" solution (this worked only for the Word-Icons at least)

What else can I do?

Creating a new user account and uninstalling Office on the old account and reinstalling on the new account worked for me. Here's the link for uninstalling

I had the same problem - quite many but not all MS office file icons, and PDF's (should be Adobe Reader icons in my case) were affected.

The problem did show up after a Yosemite clean install.

After reading bogdanbat's hint, I used "TinkerTool System 4" (from the Author of TinkerTool, but the "System" App is an independent Program which you can try in Evaluation Mode) to clean all caches (Application related caches as the interface tells). This did fix the problem for me, at least to until the first reboot.

The other solutions for cleaning the cache have not worked for me. But this one, using TinkerTool, have done great! All of my icons of docx and doc files were restored! Thanks!!

Same for me here... clean install of the latest yosemite on a brand new macbook pro ; the problem appears with various apps (not only MS) and is probably related to yosemite only... ; tried everything mentioned here without success. Hope this will be fixed soon...
