Possible Fix for "installed an unofficial game modification..." (MAC)

Post by intropella on Tue 02 Sep 2014, 09:47

This is one of my solution and hopefully this solution work!
If you have a pop error saying "unofficial game modification" this could mean that you did not install the Expansion Packs in order!

It is crucial to install the Expansion Packs in order for macs; if not, this error will occur and it will be unplayable. >:

1.) Uninstall everything! (I know it's in the pain v.v)
2.) Install EP correctly in order (by date) (Click here to see the EP in order)
3.) Advise to test (by playing) after you successfully install each individual EP.
4.) Update and Crack!
5.) Viola hope it works.

Another solution!!
Tthere could be a corrupted mod.
If so, please remove all the mods and play without using mods.

---If anyone found other possible solutions, please do reply in this thread. ---

If other problems have occur, please look through the Mac Support, to find other possible solution!

Hello Intropella,

The way you described right here is essential for being able to work The Sims 3 on Mac Very Happy The "Installation an unmodified Game Modification" usually means, if someone had to update their game before installing the latest EPs and forgot to update it again after installing all the expansions and apply the Ultimate Fix, the game detects it. It isn't directly about installing every in order, but to update the game right before applying the Ultimate Fix (whether they applied it before or not)

I am not sure game mods cause this error. But as you said, it won't hurt anyone to remove the Mods file and test the game without it Smile
