Re: Sims 3 won't run on 2015 macbook pro
The Sims 3 is not compatible on Macs which only have integrated Intel Iris graphics. If you would like to play the game on your Mac with these graphics you have to edit the GraphicsCards.sgr and GraphicsRules.sgr files. Instructions can be found here. Whilst this fix is working for some, unfortunately it doesn't seem to work for everyone.
