What kind of Mac do you have, how much RAM etc?

Try doing a clean uninstall and then just install the base game and patch it up to date. Test that it works before adding anything else. Then add an expansion pack at a time, testing after each installation. If Late Night (or any other one) keeps causing trouble you might either be adding more expansions than your Mac can handle, or else there's something wrong with that particular disc. If it turns out that the disc is to blame, you can register the game codes and download for free from Origin.

Clean uninstall/reinstall instructions

When you uninstall TS3 games on your Mac using the uninstaller, the game leaves behind stray files and isn't completely removed from your computer. These files may conflict with future installations. It is best to completely remove them. BluebellFlora's website provides a guide on how to do this:

After cleanly uninstalling, install the base game and patch it up to date. If you cannot update via the Launcher, download and apply the latest cumulative manual patch (called the superpatch) for Mac. Be sure to choose the right file - there are various 'regional' files for disc-users and one designated region 7 for Origin-users.

Check that your game works properly. Then install any EPs and SPs that you own, in order of release date.

No I have all discs, no downloads. I actually figured it out around midnight so if anyone has this problem also, this worked for me, I tried everything and this was the only thing that worked for me, its from another forum:

"I have found a solution that got rid of the Unknown Error Occurred problem that I was having on the Mac. I have The Sims 3 base game and the Late Night expansion pack for the Mac. Late Night is the only expansion pack that I have, so this solution may not work for other expansion packs. I did the following to get rid of the Unknown Error Occurred message.

1. Install The Sims 3 base game.

2. After the installation is complete for the base game, update the base game.

3. Now install the Late Night expansion pack.

4. After the installation is complete for the Late Night expansion pack, update the Late Night expansion pack.

5. Open Finder and go to your Applications folder.

6. Locate The Sims 3 folder and open it.

7. Right click The Sims 3 icon and the select Show Package Contents.

8. Now navigate to Contents/Resources/AddOns.

9. Right click The Sims 3 Late Night and select Show Package Contents.

10. Navigate to Contents/MacOS

11. Double click the bootstrap icon to run it.

Now the launcher will appear and the Late Night expansion pack will run correctly. Again, this works for sure if you are only playing the base game with the Late Night expansion pack. I am not sure if this works for other expansion packs. Hope this helps everyone."
