Re: How to restore Sims 3 previous save with no "Saves" folder on MAC?
@pinknails122 For whatever your save name is, you'll see a folder with that name and another with the same name plus a .backup extension. For example, if your save is SunsetValley, you'll see a SunsetValley.sims3 folder and a SunsetValley.sims3.backup folder. The first is from the last time you saved; the second is from the second-to-last time. If you rename that folder and delete the .backup extension (e.g. SunsetValley1.sims3), you'll be able to load it from the Main Menu.
If you happen to have multiple save folders with the same name, check their modified dates: right-click and select Get Info and look at the "Modified" entry. You should be able to tell which one is the newest and put that aside, then test the older one(s) individually if necessary. As long as you don't have two folders with exactly the same name, they can all be in the same Saves folder.
