If you use a backup program such as the macOS “Time Machine” utility then you can use it to restore the prior version of The Sims 4 before the patch. The Sims 4 Legacy Edition will support macOS Lion (10.7), please, read all the details here. I use macOS Lion (10.7) and accidentally installed the October patch for The Sims 4. You will be able to play all released packs up to and including Realm of Magic. Any packs you have purchased and have not yet installed will still be available for download from the Origin client. Yes, all packs that you have purchased and installed will still be installed. Will I be able to continue playing with all the packs I own? Yes, your existing game-saves will be preserved. WIll my progress be saved if I don’t get updates? Yes, you will continue to have access to the Gallery where you can both upload and download content. Will I have access to the Gallery if I don’t get any additional updates? Make sure not to manually download The Sims 4 updates. You will still be notified when updates are available, but you will need to manually choose to download updates. This will prevent automatic updates from being applied to any Origin games you own.

In the 'General' section, under 'Updates,' un-check the “Automatically keep my games up to date' option.

Go to the 'Origin' drop-down menu and select 'Preferences'.

To disable Auto-Update in the Origin 9 client: How do I disable automatic updates on Origin? This will allow you to continue playing the game, however, you will not receive any future updates for the base game or be able to play any additional packs released after October 3.

To prevent the update, you will need to disable automatic updates on Origin. If you wish to continue playing the game while running macOS Lion (10.7), do not update The Sims 4 with the October 3 patch, or any future game patches. On Octowe will release a patch update that will no longer support The Sims 4 on that operating system. Starting next month, we will be unable to support macOS Lion (10.7). If you currently play The Sims TM 4 and run macOS Lion (10.7) there will be important changes you need to know about. If you are a Mac user, please read the below!
