In Windows it’s the same. Though the parameter is -P (uppercase) not -p. That’s why the comment said “it’s hidden behind a startup parameter”.
As best I can tell, there’s no way to make this into a shortcut that you could just click on.
I dont know about Mac, but in Linux you can just manually make a .desktop file to have as a shortcut to call firefox -P, or better a shortcut to a specific profile with firefox -P <profile>. Though what I often do is keep a bookmark to about:profiles and open a new window from there.
