odamizu - thanks for the update. Its a few years -- like maybe 10

-- since I played with aliases on Mac. My memory is that I had to create the alias file through a dialogue, not unlike Windows not often used New->Shortcut dialogue.
But we couldn't drop files on the alias - which was the objective, maybe the program was in a bundle or something, can't recall. I gave up on it, the owner was getting anxious, even after several years with his Mac he barely knew how to drive Finder

I found a Macxpert to help him.
I think we're in furious agreement that aliases on Mac, like shortcuts on Windows, are to be preferred over symlinks for accessing programs, and for the same reasons - they usually continue to work if the target is moved or renamed.
