Instead of setData you should use writeObjects(_:) like this:

    func writeImageToPasteboard(img: NSImage)
    {
        let pb = NSPasteboard.general
        pb.clearContents()
        pb.writeObjects([img])
    }
   
    func pasteboardImage() -> NSImage?
    {
        let pb = NSPasteboard.general
        let type = NSPasteboard.PasteboardType.tiff
        guard let imgData = pb.data(forType: type) else { return nil }
       
        return NSImage(data: imgData)
    }
