I hope it will help somebody in the same situation:
I've found the same issue. It is problem of mac os and finder, as I understood.

And I've made modification of built in droplet which takes the folder as source. So - it works for me.
You need to change string
set mycmd to myapppath & " makepano " & templatepath & " " & myfilelist
to
set mycmd to myapppath & " makepano " & templatepath & " " & myPath & "*.jpg"
in droplet script and then export it as a program in krpano folder.
Probably it would be good to have such option "in box" - to put on droplet folder or set of files.
