Turn on screen sharing on Mac
On your Mac, choose Apple menu> System Preferences, then click Sharing. If you selected "Remote Management", please deselect it.
You cannot enable "Screen Sharing" and "Remote Management" at the same time. Select the "Screen Sharing" checkbox. To specify who can share your screen, choose one of the following options:
All users: Any user of your computer can share your screen, except for sharing-only users and guest users. If your Mac is connected to a network account server, anyone with an account on that server can use their network username and password to share your screen. See Let your Mac join a network account server. Only these users: Only specific users can share screens. If you selected "Only these users," click the Add button at the bottom of the user list, and then do one of the following:
Select a user from "Users and Groups", including all Mac users, except for sharing-only users and guest users. Select a user from "Network Users" or "Network Groups" (including users and groups with web server accounts). Network users and members of network groups can use their network name and password to connect to your Mac for screen sharing. To set other options for screen sharing, click "Computer Settings" and choose one or both of the following:
Anyone can request permission to control the screen: before other computer users start sharing your Mac’s screen, they can request permission instead of entering a user name and password. The VNC display program can use a password to control the screen: other users can use the VNC Viewer App to share the screen, such as on an iPad or Windows PC, by entering the password you specify here. If you choose this option, you should create a very secure password.
