Apple macOS

Steam officially supports Intel Mac, OS X version 10.11 (El Capitan) or higher.

Notarization
As of October 14, 2019, Steam will require all new macOS applications to be 64-bit and certified by Apple. If your Mac application already supports 64-bit, log in to Steamworks and select the "macOS -> 64-bit binaries included" checkbox in the "Supported Operating Systems" section of your application. This will ensure that your macOS app appears compatible to users using Steam on macOS 10.15.

You can read more about Apple's plan to end support for 32-bit Mac applications in the support articleHER.

If you're not familiar with Apple's 64-bit requirement or the macOS notarization process, read more about itHER.

If your 64-bit Mac application has already been notarized by Apple, you will also need to check the App bundles are notarized in Steamworks checkbox.

Right
Support for 10.15 (Catalina) requires adding the following permissions to your build configuration

• com.apple.security.cs.disable-library-validation(enables loading of the Steamworks SDK library and overlay library)
  
• com.apple.security.cs.allow-dyld environment variables(allows the overlay library to be injected into the game process)

You can find out more about these permissions and other app security detailsHER.

32-bit Mac-apps
Steam users who purchased older 32-bit Mac apps will still license those apps on Steam and can still access those apps in their Steam library. macOS 32-bit applications will continue to work on macOS 10.14 Mojave and older macOS versions. Additionally, Steam users are protected by Steam Play and can also play these games on other supported platforms at no additional cost. You can read more about how users can continue playing their Steam library on Mac computersHER.
