I find out the solution, I hope this will help you all.

I made a NSSliderCell class and override the function drawKnob.

class CustomSliderCell: NSSliderCell {

@IBInspectable var knobImage: NSImage?{
    didSet{
        if let knobImage = knobImage{
            self.knobImage = knobImage
        }
        
    }}

override func drawKnob(_ knobRect: NSRect) {
    
        var rect = knobRect
        
        rect.size = NSSize(width: rect.width, height: rect.height - 4)
        self.knobImage?.draw(in: rect)
    
        
}

}

just assign this class to you nsslider cell from your storyboard and change the image on your storyboard. enter image description here
