After I install my WD the screen looks like this. And it doesn’t work to push neither Backup or Retrieve, just Home and Settings. How do I move my files to my WD?

Hello dengan89,

According to the picture, you are using a previews version of the software.

Make sure to update the software from the settings tab to get the latest version available.

Also note that you will be able to use the Time Machine backup software that comes with your MAC.
