I am trying to change an icon on a regular folder in the user folder so I did what was instructed in another post - so I went to System/Library/CoreServices/CoreTypes.bundle[ShowPackageContent]/Contents/Resources Opened an icon in Preview and Edit Copy THEN went back to the folder and did Cmd+I, then clicked on the small preview of the icon and Cmd+V - nothing happens. Where did I go wrong? I used the same procedure for the HD icon... cept I went to /Library/MachineTypes.bundle/Contents/Resources to get the MacBook (Alum) icon. But no different still an icon. So, where... did, I go wrong?
