Do you get an option to uninstall when you click on the game in your games library? If so click on it then choose Revert game edition. Origin Access is not available for Mac users. Does your Mac support the current version of the game or do you need to also download the Legacy Edition? https://answers.ea.com/t5/Technical-Issues-Mac/The-Sims-4-Legacy-Edition-thread/m-p/8420037#M22694
