From the docs: ``` @abstract The default mach port used to initiate communication with IOKit. @discussion When specifying a main port to IOKit functions, the NULL argument indicates "use the default". This is a synonym for NULL, if you'd rather use a named constant. extern const mach_port_t kIOMainPortDefault ``` `kIOMasterPortDefault` is deprecated, and `kIOMainPortDefault` isn't available on Catalyst in Xcode 14. This fixes compilation by simply using `NULL` (0). Fixes [CSDK-106].
