Can my Mac Sims Data Switch Over to PC?

Yes! I was able to do this when I switched from mac to pc. The simplest way is to make a copy of your entire sims 4 folder, and either email it to yourself or use a USB to transfer the files. Then drag the folder into the spot where the game created sims 4 folder appears, and delete the auto generated folder. It should hopefully recognize it, and if not, just launch your game which will generate a new sims 4 folder, then manually drag your old files into the new folder.
