import "fmt"
type Client struct {
}
func (c *Client) InsertLightningConnectorIntoComputer(com Computer) {
    fmt.Println("Client inserts Lightning connector into computer.")
    com.InsertIntoLightningPort()
}

package main
type Computer interface {
    InsertIntoLightningPort()
}

package main
import "fmt"
type Mac struct {

func (m *Mac) InsertIntoLightningPort() {
    fmt.Println("Lightning connector is plugged into mac machine.")
}

package main
import "fmt"
type Windows struct{}

package main
import "fmt"
type WindowsAdapter struct {
    windowMachine *Windows
}
func (w *WindowsAdapter) InsertIntoLightningPort() {
    fmt.Println("Adapter converts Lightning signal to USB.")
    w.windowMachine.insertIntoUSBPort()

package main
func main() {
    client := &Client{}
    mac := &Mac{}
    client.InsertLightningConnectorIntoComputer(mac)
    windowsMachine := &Windows{}
    windowsMachineAdapter := &WindowsAdapter{
        windowMachine: windowsMachine,
    }
    client.InsertLightningConnectorIntoComputer(windowsMachineAdapter)
}

Client inserts Lightning connector into computer.
Lightning connector is plugged into mac machine.
Client inserts Lightning connector into computer.
