Re: MAC FREEZING AFTER 10 minute game play?
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
Can you post a screenshot of the in-game graphics options as they were when it last crashed.
Do you have a lastCrash report in the Sims 4 folder? If so please copy/paste the contents here.
