Hmm. Thanks for the code! It might be me but conforms(to) always returns true as the UTType(tag: machine, tagClass: .deviceModelCode, conformingTo: type) is never seems to be nil. Because of this this code will always just return the first image in the list (namely "macbook.gen2").

(Trying with Sonoma beta4)

@waydabber I experienced the same problem. The following changes to conforms(to:) seem to work.

    private static func conforms(to hardwareModelClass: UTType?) -> Bool {
        guard let hardwareModelClass, let machine else {
            return false
        }
        
        let hardwareModelUTType = UTType(tag: machine,
                                         tagClass: .deviceModelCode,
                                         conformingTo: nil)
        
        return hardwareModelUTType.map {
            $0.conforms(to: hardwareModelClass)
        } ?? false
    }

Also, this is great! Thanks for figuring this out, @kirb !

Thanks @jpavao! And sorry I didn’t get to looking at this sooner, @waydabber.
