Screens Express is a free utility complementary to Screens for iOS or Mac that grants a trusted party access to your Mac via a unique and temporary link. It ensures that the required services are configured and running properly on your Mac and configures your router so that your Mac can be accessed remotely.
You can close the connection anytime you wish.
Note: Screens Express requires macOS 10.10 Yosemite or later.
On the Mac you will be connecting to, download the app by clicking on the appropriate link:
Then, simply double-click on the Screens Express icon to launch the app.Required Service and Settings Validation
Screens Express will verify that the required settings are properly configured. If that is not the case, you will need to grant Screens Express permission to make those changes for you. Screens Express will restore those settings back to their initial state when you close Screens Express.
Once the operation is complete, Screens Express will generate a unique link, which can be shared with the person who wish to connect to your Mac. You can choose to change that link every time you use Screens Express or make that link the same on each use.
Simply select and copy the unique link or click the Share button to get a list of options:
The person receiving that link can then tap or click on that link, which will automatically open Screens and initiate a connection to the Mac.
Until a connection has been made, Screens Express is in wait mode. When an incoming connection has been detected, you will be prompted to allow the remote guest connection to continue. Click on Share Screen to let the connection go through.
From this point, the person has access to your Mac like he or she would be sitting in front of it.Closing the Connection
To close the connection, you can either Quit the app or click the Close button if you wish to close the connection but keep Screens Express running.
If you choose to close the connection, the app will need your permission to perform this action.
Screens Express was designed to only operate when it is running and will not run in the background. If you close Screens Express, your sharable link will become invalid until you launch the app again.Internet Connection

Configure Your Router Properly
Screens Express needs to open a public port on your router in order to make your Mac accessible remotely and does so through UPnP or NAT Port Mapping. In this example, we demonstrate how to enable NAT Port Mapping on your Apple router.
If you have a different router, then please refer to your router's documentation or perform a search on Google through this form:
