Remember, different operating system/different drivers, even though the hardware is the same. If you’ve Boot Camped your Mac and you can play The Sims 4 well, this is absolutely NO indication of how well the game will play in OS X. All signs indicate that The Sims 4 will be native to Mac, as The Sims 1 and The Sims 2 were. Your game thinks it’s running in Windows, not OS X. Remember that The Sims 3 runs so appallingly on Macs because EA used Cider to make the game OS X compatible. If you have a 13″ MacBook Pro (non-retina) with one of the integrated Intel cards, and it has 384Mb VRAM, you can increase this to 512Mb VRAM by upgrading the system RAM to 8Gb. The same goes for the Intel Iris and Iris Pro cards. If you have a Mac which has the Intel 3000 or Intel 4000* or Intel 5000 graphics cards, you should be fine. These are more recent and powerful than the Intel Core 2 Duo stated in the CPU requirements. If you have a Mac that has an i3, i5 or i7 processor, you should be fine. I have already posted this on my blog because so many people are asking this question.
