SimS 4 game running slow on MacBook Pro

Hi everyone. I just got the Sims 4 game and I am noticing that the game is running super slow on my laptop. It keeps lagging and when i try to do anything in the game the loading process take awhile. I am not sure if my computer is the problem. I know I have a 2015 MacBook Pro with an i5 processor. I checked on my storage and i have over 30Gb still available. My computer and the game are both up to date. Anyone know what the problem could be?
