Bought a new MBP 2017 15" with a 512gb ssd. I have a few games that I'd like to play (rarely), and need to install. I tried it once already with 120gb size, and one game (Infinite Warfare) told me I didn't have the 70gb needed to install. I was like are you kidding me! So, what is everyones recommendation that I do for size of the partition or should I use an external drive for Steam and games? Would the external drive cause any issues if it's not connected while using the laptop till I need it for the games?
