Use an iPad as a second display for a Mac
With Sidecar, you can use your iPad as a display that extends or mirrors your Mac desktop.
Get ready
Before continuing, make sure that your Mac and iPad meet the Sidecar system requirements, including that each is signed with the same Apple ID.
You can use Sidecar wirelessly, but to keep your iPad charged during use, connect it directly to your Mac with the USB charge cable that came with your iPad.
