@SarahAnn8771 Sorry for the late reply. I moved your thread to the Sims 4 Mac section.
It sounds like iCloud synced the new version of the Sims 4 folder, the one with only your newest save. You may be able to find a backup somewhere though. Open a Finder window, and click on Macintosh HD, or whatever you've renamed your hard drive, in the left panel. (If you don't see it, click "Finder" in the upper left corner of your screen, then Preferences, then Sidebar; under Devices, check the box next to Hard disks.)
In the Macintosh HD folder, open Users, then your username, and look for any folders labeled "iCloud Drive (Archive)." There might be quite a few, but start by looking inside the newest one by its last modified date. If you find a Sims 4 folder with your old saves in it, you can move that folder back to Documents\Electronic Arts on your hard drive. It's best to turn off iCloud's auto sync feature first though, so this doesn't happen again.

Thank you for you help! I looked where you stated and I could not find an old Archive of the iCloud Drive so I guess they may be gone forever. But thank you for your help.
