Sims 4 Macbook Will crash whole computer

So While im playing Sims 4 on my Macbook 13inch mid 2012, itll crash randomly and crash my whole computer as if it is having a RAM Issue. Ive tried almost everything on the site, and I have contacted EA Once (I am going to contact them again next time the support center is open, I know the hours). I have contacted Apple three times about it  and we have ruled out RAM issues, and Overheating. The only thing we can think of is that its the programming? There is also this file on my computer called lastException. (some numbers). txt. 

The apple guy and I looked at that and he seemed kinda concerned but asked me to ask EA about it. Especially since it comes up when I search for sims 3 in my computer files, though this .txt file is connected to sims4. 

Apple and I think it has to do with programming because when it crashes (and we went through the logs), the computer (today at least) reported that Sims4 was using too much of the CPU i.e. "burning CPU" or "Burning through CPU" meaning it was using more than 50% of the CPU. 

Anyone have any ideas on what I can do? My computer works fine normally, I just want it to stop crashing, so I can play sims peacefully... 

Thanks,
