+[h1]Steam macOS 11 Support[/h1]
+
+On October 15th, 2025, Steam will officially stop supporting macOS version 11 ("Big Sur"). After that date, the Steam Client will no longer run on this version of macOS. In order to continue running Steam and any games or other products purchased through Steam, users will need to update to a more recent version of macOS.
+
+This change is required as 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 12 and above.
+
+We strongly encourage all macOS 11 users to update sooner rather than later. Apple ended security updates and technical support for macOS 11 in 2023. Computers running these operating systems, when connected to the internet, are susceptible to new malware and other exploits which will not be patched. That malware can cause your computer, Steam and games to perform poorly or crash. That malware can also be used to steal the credentials for your Steam account or other services.
+
+Users of macOS version 11 can find more information on upgrading macOS [url=https://www.apple.com/macos/how-to-upgrade/]here[/url].
