Steam will no longer support macOS 10.11 and 10.12 after September 1, 2023

On September 1, 2023, Steam will no longer support macOS versions 10.11 (“El Capitan”) and 10.12 (“Sierra”), meaning that the Steam Client will no longer run on those versions of macOS. Users wishing to continue running Steam and any games or other products purchased through Steam will need to update to a more recent version of macOS.

This change is due to the fact that core features in Steam rely on an embedded version of Google Chrome, which no longer functions on older versions of macOS. In addition, future versions of Steam will require macOS feature and security updates only present in macOS 10.13 and above.

Steam has encouraged users to take the necessary steps to update their systems in order to continue enjoying their content. The company has also offered support and guidance should users have any questions or concerns about updating their macOS.

Steam is committed to providing the best gaming experience possible, and this change is necessary in order to ensure the highest quality of service to its users.
