Dock icons are missing after installing High Sierra
I installed High Sierra on my iMac 2011 Middle today. After installing, many of my dock icons are missing... I have tried some things I found (Terminal command lines, removing icons from dock and take back from applications), but nothing changed.
Is there anyone who experience the same? Is there anything that could fix this problem? Mainly mac icons are missings, like app store, facetime, photos, messages...
In the application folder of finder the icons are displayed correctly.
iMac, macOS High Sierra (10.13.1)
