Friendly greetings !
I'm on a MacBook Air M1, using Xcode 13.1, Swift. The full source code is below, as a MaOS Console Application
import Foundation
import Metal
import MetalKit
import simd
guard let device : MTLDevice = MTLCreateSystemDefaultDevice() else {
fatalError("could not create metal default device")
}
let queue = device.makeCommandQueue()
print("Hello, World!")
The full output, running in debug from XCode is :

Hello, World!
Program ended with exit code: 0
Running the sample "MacOS Game" default code (the one with the rotating cube) also give this "Zero Metal services found".
- What's a "metal service" anyway ? Googling for it obviously give me unrelated smithing service offer =^_^=
- It's not even "Metal Service not found" but, "I found Zero Metal Services", whatever that's supposed to mean ?
- is it "I didn't find any metal service" or is there a thing called "Zero Metal" ?
I can query the metal device name and it get me "Apple M1". No problem, everything seems to work fine (so far).
But what's the meaning of this message please ?
