Re: Gaming on MacBook Pro using external SSD?
Please can you provide more information about your Mac. Instructions on how to do so and what to provide here - http://answers.ea.com/t5/The-Sims-Mac/READ-FIRST-Sims-4-Mac-Help-Guides-and-Troubleshooting/m-p/4612396/highlight/true#M162
You can install the base game and all packs on an external provided you go into the Origin settings and select the external as the install location.
You cannot store the Sims 4 folder where your saves, CC and other user files are located on an external drive as the file path must be Users > [your user account] > Documents > Electronic Arts > The Sims 4 but you could try these steps for syncing saves across multiple Macs using a cloud service. Just ignore the instructions on setting up the saves on the second Mac.
