You can make yourself accessible to all users who have your permission, or restrict access only to certain users in your network. If you want to open your screen to VNC users who have the password to your session, click the Computer Settings button.

 

You’ll need to activate your screen sharing session for other Macs to enter it. The other Mac will also need to know your computer’s name and network address. You can find this on the right under the Screen Sharing: On heading.The name should look something like Jane’s MacBook Pro, and the address should be vnc://[IPAddress] or vnc://[Name.Domain].

 

When you have the details, send them to the remote user, and the procedure is quite simple.
