Yep, you would install the Victoria 3 Base with the .SIT file for Mac OS X. It has an installer program so you don't have to do anything manually this time. Remember that Victoria 3 Base just has very basic morphing capability and no clothing or textures. Most of the morphs in Free Stuff need the DAZ morphs to work (which you need to pay for), but they often come with textures, too. Only occasionally will you find a free morph that doesn't depend on DAZ's morphs. You'll have better luck finding free clothing for her. There's a fair amount of stuff out there, but it depends on what you're looking for.
