MetalPlugin Issues: MetalPluginName property or is of the wrong type

Question

I have been getting two messages on running my application. The app not only launches but functions as it should, however, I would rather sort the issues now rather than some crash in the future.

The messages are:

1. Unable to locate MetalPluginName property or is of the wrong type
2. +[MTLIOAccelDevice registerDevices]: Zero Metal services found

Could anyone help with the messages and how to remove them.

Thanks a lot!
