Apple started including screen sharing almost 20 years ago in its macOS operating system. This means that if you have multiple Macs at home or in the office that are also on the same local network (wired, wireless, or both), you can watch or control what’s happening on that Mac on that network. Some regular users don’t know it exists because they’ve never needed to use it.
On the other hand, if your Mac is running very slowly, you might want to improve its performance with the tips we offer here.
It’s not entirely straightforward to set or access this option, as it requires changes to both sharing the Mac and finding the right place on the Mac that’s viewing the other’s screen .
This can be useful if you have multiple Macs in different locations or a Mac without a keyboard and mouse used as part of a home A/V system, or one without a head (display) and inputs deployed as a server.
To configure this on the Mac that can be seen or controlled
- Go to ‘System Preferences > Sharing’.
- Check the box next to “Share screen”.
With the “All users” option selected, anyone with an account on the computer can access it remotely over the local network. You can limit it, as with most other sharing services, by selecting users and groups.
On any other Mac:
Go to the Finder and select the Mac’s name in the sidebar of any Finder window. (Choose ‘View > Show Sidebar’ if you don’t see the sidebar.)
- In the upper right corner of the window, click “Share screen”.
- macOS launches the “Share Screen” application. Log into your Mac with your credentials on the screen that appears.
- The other Mac will get a message saying “Your screen is being monitored” or two overlapping rectangles in the system tray to indicate remote sharing.
If you don’t see the Mac you want to see in the sidebar, in the Finder for this computer, choose “Finder > Preferences” and make sure “Hello Computers” is checked under “Show these items in the sidebar” .
