Sims 3 ‘Unknown Error’ fix – El Capitan, Sierra, Late Night & Ambitions related

This is the biggest Mac/Sims 3 issue at the moment, apart from the unsupported graphics cards issue which EA STILL haven’t fixed after nearly 4 years…

The Unknown Error is a magical mix of Late Night and/or Ambitions trying to be installed onto a Mac running macOS 10.11 El Capitan or 10.12 Sierra. It’s that simple. We have a thread running over at AHQ where people are posting about it and yesterday a rather super person called coreylamalva414 posted a solution which appears to actually work (go and show him some love if it works for you 💚). His instructions can be found hereGood luck!

Edit – coreylamalva414 has uploaded a very helpful video to walk you through the fix:
