Hi
There are two things you can try.
1.Go into Applications on your Mac's hard drive and look in the folder called “The Sims 3”. This is the location from which your game actually launches (as opposed to a similarly named folder within Documents, which is where your saves and other data are stored). In the folder in Applications you will see the shortcut icons for the base game as well as any expansions or stuff packs installed. If you can see the icon for the game that has failed to properly download from Origin, try right clicking on it and this should give you the option to show the original file. You can move the original files to the trash from there. This may allow you to commence a re-download from Origin. (Many thanks go to Tremayne from TS3 Mac forum for this suggestion.)
2. Look in Preferences in the Origin client and find the game installers. Delete the files relating to TS3. Log out of the client, then back in, then you may be able to start redownloading.
If this does not work, or if the icon is missing from the “The Sims 3” folder in Applications, then you may need to completely uninstall and reinstall.

The problem is that the EP never ACTUALLY installed. It stops in the middle of the install with 4 seconds left. I've retried about 5 times now and each time I have to do a hard shutdown of my laptop by holding down the power button. I've already uninstalled all of my other expansion packs and have not redownloaded them yet. But since this EP didn't ever install, I can't find the icon to uninstall it. And since I can't uninstall it, I can't redownload it. I think the problem is that the download was corrupted, so if I could un-download it and redownload it I think it might work... I just don't know how to do that.
