    I can run 2 instances of my app by launching the 2nd using open -a. Now what I would really like to do is make it easy for me to visually differentiate the 2 instances by giving the 2nd version a different icon.

    Could I make a new icns file and somehow assign it with the -b option which is "Opens with the specified application bundle identifier". I'm guessing the bundle identifier includes the icon? Is this possible?

    Thanks in advance for any help. :)

    What application do you want to run two instances of? I have duplicated Movist two times and can run three instances of it, but I guess, not many applications allow this that easily.

    I'm using Ableton Live. I use the duplication technique at the moment but then I came across this -a method. The app is nearly 2GB in size and gets updated quite often (and has a script inside the package that independently needs updating often). Would be nice to have just one copy on disk that get instantiated twice.
