Research direction

Start in GoogleSignIn/Sources/GIDSignIn.m and trace the App Check code guarded by TARGET_OS_IOS && !TARGET_OS_MACCATALYST, including the GIDSignIn.sharedInstance.configure path. Compare the existing platform conditions and determine the macOS-compatible entry point. Done means macOS apps can enable App Check through GIDSignIn.sharedInstance.configure or an equivalent method.

Description

enhancement triage

Is your feature request related to a problem you're having? Please describe.
App Check is currently not supported on macOS. The GIDSignIn.sharedInstance.configure method, which is required to enable App Check, is only available on iOS.

Looking at the source code, App Check related code is wrapped in #if TARGET_OS_IOS && !TARGET_OS_MACCATALYST, which confirms that macOS is intentionally excluded from the current implementation.

Describe the solution you'd like
Please add App Check support for macOS so that GIDSignIn.sharedInstance.configure (or an equivalent method) can be called on macOS as well.

Describe alternatives you've considered
No alternatives have been found. macOS apps are currently forced to run without App Check.
