r=me, but I think you could use an existing FileSystem function instead of the raw 'stat' operation.

You don't need to include this if you use , FileSystem::fileIsDirectory

> Source/WebKit/UIProcess/Cocoa/WebProcessPoolCocoa.mm:211
> +    static bool isInternal = !stat("/AppleInternal", &st);

I think it might be better to do:

static bool isInternal = FileSystem::fileIsDirectory("/AppleInternal", FileSystem::ShouldFollowSymbolicLinks::No);

Either way it’s not the recommended way to test whether a computer is running the Apple-internal version of macOS. See OSVariantSPI.h in WTF.
