Clear the icon cache on a Mac when you start seeing generic icons in Finder or the Dock

mac-clear-icon-cache.sh

sudo rm -rfv /Library/Caches/com.apple.iconservices.store; sudo find /private/var/folders/ \( -name com.apple.dock.iconcache -or -name com.apple.iconservices \) -exec rm -rfv {} \; ; sleep 3;sudo touch /Applications/* ; killall Dock; killall Finder

I've a blank icon in the Finder
for the Time Machine's drive.
I've shortened your command
but it didn't work as expected.

sudo sh -c "rm -frv /Library/Caches/com.apple.iconservices.store;\
find /private/var/folders/ -name 'com.apple.*icon*' -exec rm -frv {} \;"

It even made the specific Google Drive Icon disappear...
although it came back by just restarting the Finder again.

My girlfriend updated to Big Sur two weeks ago, and recently her Dock icons disappeared, together with some icons in the system preferences pane. Running the suggestion at the beginning of this thread:

sudo rm -rfv /Library/Caches/com.apple.iconservices.store; sudo find /private/var/folders/ ( -name com.apple.dock.iconcache -or -name com.apple.iconservices ) -exec rm -rfv {} ; ; sleep 3;sudo touch /Applications/* ; killall Dock; killall Finder

did fix the Dock icons. Let's hope that she will be spared from more initial Big Sur bugs, happy I didn't update yet... Any other suggestions are welcome!

Worked for me, Mojave 10.14.6, thanks!

Thanks a bunch! All my css files had somehow gotten associated with Tor and the onion wouldn't go away from the file icons even when I associated them with sublime editor by force. This helped get rid of the Tor onion and get the sublime icon.

Does this clear the cache for all user accounts or only the one you run it under? (Update: never mind, it does!!! It’s fixed!)

Thanks for this.

Works fine !

Thank you! It works for macOS 12.3!

this fixed my files set to open with VLC having generic white icons :D

I also did this brew cask install qlvideo >D

The OP didn't help me, but installing qlvideo does work as a workaround, on macOS 13.0 Ventura. (though the command has changed)

brew install --cask qlvideo

It worked for me. Thanks for sharing.

I'm on a MacBook Pro 16-inch 2023 (M2 Max) with macOS 13.3.1.

Worked for me on 14.5 beta on M2 MBA. Thanks!

Running the sudo rm -rfv /Library/Caches/com.apple.iconservices.store command was enough for me (plus running sudo killall Dock; killall Finder). It makes sense to remove a cache. On the other side, I see very dangerous to remove anything from inside the /private/ folder, which is a sensible folder for the stability of the operating system.
