Where do I put worlds so they show up in my game?

I didn't put this in Mac, because I am assuming that some people don't use the World Builder but install custom worlds somehow. But I have the problem because I use a Mac and the World Builder isn't available for it.

I want to install an empty version of Sunset valley. I have one installed in the Saves folder, but it won't show up in my saves. So I just wondered where I should put it so it shows up.

Custom worlds are sims3pack files, and are installed as any sims3pack is, using the Launcher.

OK. I finally found a world that required no EPs and I just did this. I assume the old .saved game files are obsolete. I mean.. when I saw that they said obsolete in the title, I assumed that just meant that most people didn't need it. I didn't know that meant it wouldn't work anymore.
