Snow Leo on Intel Mac here. It had the last official release of limewire installed. I uninstalled it and removed receipts and preferences which might remember that install. Could not find any further file, where information about that install is stored. Nevertheless, the installer still tells something like „On your volume had already been installed a newer version, you cannot install this one.” - Well, and after loading the installer to the USB-stick: The installer installs on the stick, but starting limewire produces a limewire sign showing up for a moment in the dock and disappears. No further positive effect. Any advice? Or in such case stay cool and just use another client for a while?
