I tried to install "Macbuntu" which is not compatible with 13.04 and I don't know why? But I used force option on command line nothing changed so I uninstalled "macbuntu". Now the problem is that the top menu just disappeared. For example when I'm using sublime_text or Chrome there is no menu option (File, Edit, etc..) on the panel. I tried using unity --reset-icons
option but it didn't work. Any help will be appreciated.
