Hi, Eric, thank you a lot fot the quick answer.
I followed your first advice (killall Dock in terminal), but it didn't work:-/. The icons still stay in basic settings. If i change them (delete/insert some my icons) after log out/in it became the basic setting: (from left to right) Finder icon, launchpad icon, and so on.
Than I searched for the folder through "Go to Folder", than ~/Library/Applications Support/Dock, but it can not be found.
The file .db. is although in Library->Preferences not there….
I have to say this problem came after OS X ML update the day before yesterday and after the installation of "MacKeeper" software. I deleted the software because the free trial version makes only one screening and during this it probably cleaned something from my Mac which may causes this problem now.
…?!? I do not know...
Do you have more suggestions/advices?
thanks,
best regards
