Unfortunately, as the MacOS Sonoma beta (14.0) was released in June 2023, we can’t guarantee the stability of the Football Manager that runs on this OS. Therefore, we strongly suggest you only update your device to Sonoma if you have a secondary device that can run Football Manager.
If you have any technical issues with the FM23 on MacOS Sonoma, we recommend you roll back your OS to the previous version.
If you still have issues running Football Manager after rolling back your OS, please get in touch with our support team and we will try our best to help you.
