The Sims 3 64-Bit Keeps Crashing on Mac

1qotcb37p81g​  What year is your Mac, and do you have a 13" or 15" model?  I ask because that will let me figure out exactly what processor it has and therefore what graphics chip.

Please also let me know how much free and total storage you have on your Mac's internal drive, which you can see by clicking the Storage tab under About This Mac.  And I'd also like to know whether iCloud Drive is active and specifically syncing the contents of Documents.  You can check by opening System Settings > Apple ID > iCloud > iCloud Drive Options.  Don't check the box if it isn't already; I just want to know what your current setup is.
