Is there a way of getting a Mac's icon given its model number?

Question

I know you can get the current machine\'s icon from cocoa using the following code:

NSImage *machineIcon = [NSImage imageNamed:NSImageNameComputer];
<

Here's a solution in Swift, but it uses a private API so remember that it might be subject to undocumented change and App Store rejection.

struct MachineAttributes {

    let privateFrameworksURL = "/System/Library/PrivateFrameworks/ServerInformation.framework/Versions/A/Resources/English.lproj/SIMachineAttributes.plist"

    var model: String?

    var attributes: [String:AnyObject]?

    var iconPath: String?

    init() {
        self.model = getModel()
        self.attributes = getAttributes()
        self.iconPath = getIconPath()
    }

    init(model: String) {
        self.model = model
        self.attributes = getAttributes()
        self.iconPath = getIconPath()
    }

    private func getModel() -> String? {
        let service: io_service_t = IOServiceGetMatchingService(kIOMasterPortDefault, IOServiceMatching("IOPlatformExpertDevice"))
        let cfstr = "model" as CFString
        if let model = IORegistryEntryCreateCFProperty(service, cfstr, kCFAllocatorDefault, 0).takeUnretainedValue() as? NSData {
            if let nsstr = NSString(CString: UnsafePointer(model.bytes), encoding: NSUTF8StringEncoding) {
                return String(nsstr)
            }
        }
        return nil
    }

    private func getAttributes() -> [String:AnyObject]? {
        if let dict = NSDictionary(contentsOfFile: privateFrameworksURL) as? [String:AnyObject],
            let id = model,
            let result = dict[id] as? [String:AnyObject] {
                return result
        }
        return nil
    }

    private func getIconPath() -> String? {
        if let attr = self.attributes, let path = attr["hardwareImageName"] as? String {
            return path
        }
        return nil
    }

}

If you don't know the model:

let myMachine = MachineAttributes()
if let model = myMachine.model {
    print(model)
}
if let iconPath = myMachine.iconPath {
    print(iconPath)
}

If you know the model or want to use another one:

let myNamedMachine = MachineAttributes(model: "iMac14,2")
if let iconPath = myNamedMachine.iconPath {
    print(iconPath)
}
