Opening a new copy of an application on Mac

Mac doesn’t like you to open multiple copies of an application. If you try to open a new copy, it will switch to the old copy. If you want to open a new copy this is what you need to do:

Fire up the terminal and type:

$ **open -n /Applications/<name of application>.app**

Saw that little -n switch? That’s the one which tells Mac to open a new copy.

By day, I ship code at MetaGeek, by night, I hack on my personal projects, and finally, when I get some off time in between, I also serve as a CTO for ClockworkEngine, LLC where so far we have launched two products - Spyglass and LightPaper. Call be a serial coder if you want.
