I have a MacBook Pro (but am a bit new to Mac). I installed the new Logos 5 engine (haven't yet upgraded, just the new engine). However, the old Logos 4 icon is still on the desktop. Is there a way to remove it? I can't drag it to the trash, and I don't know if I can fully delete the program and still have everything I need. Any thoughts? Sorry it's a bit more of a Mac question, but does relate because if I can remove the whole and free up disk space that would be great too. Thanks.
