You can also copy and paste the command. To paste into the terminal, use the “Edit” Menu, or press Ctrl+Shift+V
You may be prompted for your

Once you see the command above has finished, enter in the following command to enable DVD playback:

After enabling codec support, it’s recommended to restart your computer. Click on the Device Menu (Gear Icon in the upper-right corner of your screen), then click on “Shut Down…”. Then, click on the restart item in the shutdown overlay.
