When running on an older Mac OS, the application falls back to running OpenGL and displays a warning message explaining that it is deprecated; but allows you to continue and load it up.

When submitting to Apple, the reviewer rejected the application because of this warning. Now I have spoken to one of the Unreal Staff who said I am able to suppress the warning message.

I found the setting that can be used, however when I tested it, it didn’t work. (see below) I added the MacOpenGLDeprecated=True to the GameUserSettings.ini

Anyone know how I can do this (without removing the message popup from the engine source) ?

```
const static FString ConfigSection = TEXT("SuppressableDialogs");
     
 bool bShouldSuppressDialog = false;
 
 if (GConfig)
 {
     GConfig->GetBool( *ConfigSection, TEXT("MacOpenGLDeprecated"), bShouldSuppressDialog, GGameUserSettingsIni );
 }
 FText LocalizedMsg = FText::Format(NSLOCTEXT("MessageDialog", "MessageMacOpenGLDeprecated","Support for running Unreal Engine 4 using OpenGL on macOS is deprecated and will be removed in a future release. Unreal Engine 4 may not render correctly and may run at substantially reduced performance."),Args);
         
if (!bShouldSuppressDialog)
 {
     FPlatformMisc::MessageBoxExt(EAppMsgType::Ok,
                              *LocalizedMsg.ToString(),
                               *NSLOCTEXT("MessageDialog", "TitleMacOpenGLDeprecated", "WARNING: OpenGL on macOS Deprecated").ToString());
}
else
{
             UE_LOG(LogRHI, Warning, TEXT("%s: %s"), *NSLOCTEXT("MessageDialog", "TitleMacOpenGLDeprecated", "WARNING: OpenGL on macOS Deprecated").ToString(), *LocalizedMsg.ToString());
}
```

When you added “MacOpenGLDeprecated=True” to GameUserSettings.ini did you ensure that it was within the “[SuppressableDialogs]” section? It should look like:

```
[SuppressableDialogs]
MacOpenGLDeprecated=True

```
