How to run multiple instances of Maya in OSX

I'm writing this because a friend has asked me twice about how to open more than one Maya in Mac OSX, so I think this may help other artists to run multiple instances of Maya because sometimes is handy to do it.

If you are not a Mac user you may ask; Is it not as easy as double click the Maya.app icon again? No, unfortunately that would send you to the already running one.

The solution relies on the open command, so it is as simple as to run the terminal app and execute the following:

open -n /Applications/Autodesk/maya2013/Maya.app

The -n part does all the trick
-n  Open a new instance of the application(s) even if one is already     running.

If you want to learn more about the open command, type man open in the terminal

Yes, BSD General Command Manual (your beloved Mac is Unix), the open command first appeared in NextStep.

But not everybody loves to open a terminal just to run their Apps, right? so let's use one of the most useful and powerful yet not known Apps in Mac OSX, The Automator


Once you run it, select Application

And then find Run Shell Script in the Actions section and drag and drop it to the right side


And put open -n /Applications/Autodesk/maya2013/Maya.app inside the box
Save it


And now you can change its icon and put it in your Dock


And voilá



You can now easily open as many instances of Maya as your RAM let you.
Of course this behaviour doesn't happen in all the DCC Apps, for instance with NUKE you just have to open or create a new comp.
