How can I run two instances of WhatsApp on a Mac? I have two phone numbers for two purposes and I would like to run two native WhatsApp clients in parallel on my Mac.

I don't want to use the browser (or two browser windows) since I prefer the native Mac OS apps.

How can I do that?
Simply open terminal and run this command:

/Applications/WhatsApp.app/Contents/MacOS/WhatsApp /secondary


Two remarks:


The app seems to crash if you subsequently close the terminal (even if you use &amp;) so keep your terminal open. Sudo may solve this (as seen here) but I didn't really try.
If anyone knows how to make it launch from Spotlight, please share your ideas. I would love to improve on this method and make it easier to use.
