[MAC] My Sims 3 game crashes after 5-10 minutes [ Edited ]

[shesogray]

• I just bought a Sims 3 download but I can never play it because it always crashes while I'm designing my character (during the first 5-10 minutes).
•  I have a MacBook Pro (Retina, 13-inch, Mid 2014), 2.6 GHz Intel Core i5 processor, 8 GB 1600 MHz DDR3 memory, and  Intel Iris 1536 MB graphics.  I'm not trying to play any expansion packs or anything complex - just the Sims 3 game.
