Share your screen using Back to My Mac

If you have an iCloud account, and you have several computers connected to the Internet, you can share the screen of one computer with other computers.

For example, if you have a Mac at home that’s connected to the Internet, you can share its screen with a Mac you use at work. You can control that Mac, move files and folders, open or close apps, and even restart it.

Back to My Mac requires a router that supports NAT Port Mapping Protocol (NAT-PMP) or Universal Plug and Play (UPnP) to share services.

Use iCloud to share your screen

Follow these steps for each computer whose screen you want to share.

  1. Choose Apple menu > System Preferences, then click Sharing.
  2. Select Screen Sharing.

    If Remote Management is selected, you must deselect it before you can select Screen Sharing.

  3. Next to “Allow access for,” choose all users, or only listed users. If you permit only listed users to have access to the screen, click Add (+) and Remove (-) to edit the list.
  4. In System Preferences, click Show All, then open iCloud preferences.
  5. If you aren’t already signed in to iCloud, enter the Apple ID you use with iCloud, then click Sign In.
  6. Select Back to My Mac.

To stop sharing your screen using Back to My Mac, open iCloud preferences, then deselect Back to My Mac.

Connect to your remote Mac

  1. To see your remote computers in the sidebar of a Finder window, choose Finder > Preferences, click Sidebar, then select Back To My Mac in the Shared section.
  2. Open a Finder window. If no shared computers appear in the Shared section of the sidebar, put the pointer on the word “Shared” and click Show.
  3. Click the remote Mac, then click Share Screen.

    If you don’t see the Mac you want, click All to see all the available computers, double-click the one whose screen you want to share, then click Share Screen.
