I can't delete any service, i have a bunch of useless graphic converter thing that i dont want. I have unchecked them in System Preferences but the next time i launch System Preferences they are still Checked. I have look in The System Library Services Folder, The User Library Services Folder and The General System Library Services Folder. When clicking "Show in Finder" i just get the app graphicconverter. I also ran this terminal command resetting these preferences Code: chmod -RN ~/Library/Preferences I also reset all the home folder permissions. I also repaired permissions.
