Import of IOKit for macOS will not work

[DelphiWorlds]

In case anyone else tries, import of IOKit will not work because Apple do not provide all required header files (At this point it is unknown as to why)

You might be able to succeed if you locate the missing header files, such as possibly from here:

https://opensource.apple.com/source/xnu/xnu-7195.81.3/iokit/IOKit/

..and copy them into the relevant places in the Headers folder of the IOKit framework
