Hello, i have a Mac. and this is the second time this have happend to me. Everytime i update my mac, i lose all my game files. First time this happend I lost all my saves and i had to start over. This second time it happend same thing, my mac updates its software and i lose my saves. but now i have the original save that i lost the first time. I have used alot of time on the 2nd save and i would like my sims back.

the save files that i have right now its called:

Slot_00000004.save

Slot_00000004.save.ver0

Slot_00000004.save.ver1

And those are the only save files that i currently have on my mac, and i had like atleast 7 sims families on the "2nd" save and on the first save that i now have back i only got like 1-2 sims families.

Can anyone help me?
