Yeah, time to switch to a PC. A Mac can't do much in the way of MC or other games. Overclocking your CPU x3 is pretty bad, and your fan really shouldn't be sputtering like that. I recommend looking at /r/pcmasterrace if you're planning on building your own, or even just buying a prebuilt.
I prefer Sims 4. I played Sims 3 but that really has aged. I like Sims 4 because it really revitalized the mood of sims. Having multiple emotes influence the mood of your Sims really makes it feel like a bit of a minigame, and I really like Get To Work's interactive jobs.
Both are unique games. This is like comparing potatoes to oranges. It just doesn't work. Plus, this discussion feels like it's from 2013, when childish fights about two creation games were sweeping the nation.
