Message : Allow choosing EAGL or CGL at runtime Dean Jackson made this change downstream in WebKit: https://bugs.webkit.org/show_bug.cgi?id=216722 Change ANGLE to dynamically load either EAGL (OpenGLES) or CGL (OpenGL) depending on both compile and runtime configurations. Intel Mac -> CGL Intel Mac Catalyst -> CGL Intel iOS Simulator -> EAGL iOS Device -> EAGL Apple Silicon Mac -> CGL Apple Silicon Mac Catalyst (with Mac app) -> CGL Apple Silicon Mac Catalyst (with iOS app) -> EAGL The trickiest bit is Apple Silicon Mac Catalyst, which depends on the type of the application it is attempting to run. In that case ANGLE must compile both the CGL and EAGL interfaces and then pick one to use after launch.
