games won't open with el capitan

Hello, robpti.

Thank you for visiting Apple Support Communities.

I see you are having an issue with games after the update to 10.11.1. I would need more information on this issue to provide a better answer. Does this happen with all games? Can you test to see if you experience this issue with any other applications? You may also want to check with the developer of the game to make sure that it is compatible with the update. In the interim, here are a couple troubleshooting articles that may help with this issue.
