Screen Sharing for Mac OS X

The following directions are for enabling and using Mac OS X Screen Sharing for on-campus and off-campus remote access. Mac OS X's Screen Sharing uses the VNC protocol.

  • If you are a Windows user, please clickhereto learn how to use the VNC program on that platform as well.
  • Before you start screensharing, if this is for a college-owned computer that is on-campus, please contact the helpdesk (x3333, orhelpdesk@wellesley.edu) and request a static IP Address for the computer whose screen you want to share.

  • To use Screen Sharing to connect to your office computer, your office computer must stay powered on, and not go into sleep or hibernation modes. You may put the display to sleep.
