Unfortunately, some of my icons are missing and replaced by the deafult icon. This happens randomly and with all kind of different apps (App Store, system, internet) and I don't know what to do.
MacBook Pro with Retina display, macOS High Sierra (10.13.2)
If it's both in the Dock and your Applications folder then reset launch services database:
Launch Terminal in your Utilities folder.
Triple click anywhere on the following line to copy entire line. Then, at the prompt copy & paste this command:
Then press return. Wait for the cursor to return to the command line.
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain u -domain s -domain l -v

Is this just in your Dock, or is it in your Applications folder also?
If just the Dock, try resetting the Dock:
From your Finder "Go" menu hold the option key and choose Library. Then go to Preferences folder and trash this file:
com.apple.dock.plist
This will reset your Dock to default and you'll need to set it up the way you like it.
Thanks but this didn't solve my problem neither.
I reinstalled macOS and I had to reset the dock after it and now everything is working fine again.
There was also a strange image error for maybe half a second when activating the monitor. It's also fixed.
Thank you, it’s not only in the dock, it’s also in the application folder and the launchpad. I did already reset the dock. After that, other icons were missing than before, maybe I’ll try a reinstallation of the Is the next days.
