Wrong (generic) Mac dock application icon I have the following problem since upgrading to OS X 10.13.1 High Sierra on MBP 2017.  A generic icon is shown for nearly all my apps. See the image below. Does anyone know how to fix this and get the applications icons back?
Try running this shell script sudo find /private/var/folders/ -name com.apple.dock.iconcache -exec rm {} \;
