    Hello, I have been experiencing the same issue you have for days for the same exact game so I can understand how frustrated you are. Luckily, I just found the solution. Bear with me, it might be kind of confusing but i'm going to try and explain this to you as easy as possible. Go to Applications > Sims 3> right click on Sims 3 and hit show package contents. Within Show package contents,  Go to contents> Resources> Add ons. All of your installed expansion packs should show, even the ones not working. Right click under the ones not working for you (So late night or ambitions) Within THAT folder, I want you to right click on Late night/ambitions and again right click and go to Show Package Contents. This time, I want you to go to Content> Resources> Transgaming. Inside Transgaming, open Program Files> Electronic Arts> and within that should be folders for your expansion packs. Copy the WHOLE FOLDER of the game that isn't working (Late Night/Ambitions)

    With your copied folder, go back to Applications> Sims 3> Show package contents> Resources> Add ons. Normally, when your launcher opens, its an icon of one of your expansion packs. For me, that is Island Paradise. So, I right clicked on Island Paradise>Show Package contents>Content?Resources>Transgaming>Program Files> Electronic Arts> and you will find yourself at the folders with expansion packs. Notice how Late Night/Ambitions is not there? PASTE the folder you copied into there. Once both Late Night and Ambitions is working, try relaunching the launcher and you should be good to go! I hope I helped!

Hi,
When I am listing my directions above, I am basically saying that you have to dig deep into your folders in the applications section of "finder" on your macbook pro. So if you go to "Finder" and "Applications" You should see a Sims 3 folder. Follow my directions above after you have reached that sims 3 folder.

    Should i install all the Ep's i have then? Even tho it doesn't work on my base game and try from there? I've re-installed about 4 times now and the first two times the base game ran fine but i thought i should delete it just in case but now nothing is running

      Yes, install all of your sim games despite you not being able to open launcher. Once you follow the directions above, you should be able to open your sims launcher and play

    I thought for sure it worked but when I go into the transgaming>Program Files>Electronic Arts> folder with the expansion packs that you said should not be there is not the case; the expansion pack file is in this folder and still getting the unknown error.  Any other suggestions?

      You're correct when you say the folder is there, for example, the late night folder should be within the late night app. However, if you go into the expansion pack that normally launches, is it in there along with all the other expansion packs? Are ALL your expansion packs you own in the folder with the one that launches?

        Hey!
        Basically when I install sims ambitions the actual icon isn't where every other one of my games is and I have doubled checked but I can't uninstall through the launcher like the uninstaller
