Is this OK for mac or just PC?

Thanks for the link. I'm not talking about the usual game update patch, these are mods like the nudeskin etc. I don't know how to install them.

It wasn't winrar ftr it was unrarx but whatever. I'm no closer to figuring this out.

I hope this isn't the 50th thread on this topic, but I searched and found nothing to help me.

I downloaded a patch.  It comes as an .rar file which I open with winrar.
now it reads "...packed.package" I open it with Sims 3
...nothing happens.
I get that window with all my downloads but it's not there.

On windows I know you all put the patch into a certain folder but this isn't possible on a mac.

What am I missing here?

I'm sorry to post this but there aren't very reliable instructions included with the game.
