Unity 5.26.0 - Improvements to macOS OAuth Flows

Firekeeper

• Native OAuth Integration: Added support for OAuth (social login) flows on macOS standalone builds using ASWebAuthenticationSession, integrated into the default CrossPlatformUnityBrowser.
• Universal Binary Support: Ships with an optimized native plugin (libMacBrowser.dylib) containing both ARM64 and x86_64 architecture support.

• Enhanced Security & UX: OAuth flows now use the system’s native web authentication session for better security, user experience, and compliance with App Store review guidelines.
• Improved Redirect Handling: Redirects now deeplink back into the app instead of following the Desktop Windows–style flow.
• Refined Platform Detection: macOS is now properly detected and handled in authentication workflows.
• Browser Selection Logic: Updated to ensure seamless use of the native macOS session.

• Native macOS plugin (libMacBrowser.dylib)
• MacBrowser class implementation
• Build instructions for compiling the plugin
• Updated browser selection logic for macOS builds

Note: This functionality only works in builds. In the Unity Editor, the original flow will still open a full browser.
