Open two files simultaneously on Astah on Mac

Here’s a little tip for Mac users for how to open two .asta files at the same time on Mac.

Run either command below in Terminal while one Astah is already open.

To launch another Astah:

open -n /Applications/astah\ professional/astah\ professional.app
(Let it point to your Astah app file)
* The text in orange will be replaced with the edition you have. (sysml, community or gsn)

To launch another Astah with a specific file opened:

open -n xxx.asta　(eg: open -n /Users/xxxx/Desktop/Class.asta)

* The text in orange will be .asml if you are using Astah SysML and .agml if you are using Astah GSN
