How to Control Your Mac Remotely
You can use Snow Leopard’s Screen Sharing feature in iChat to make a remote connection from another Mac to your Mac. However, you’re not limited to using just another Mac using Snow Leopard and Screen Sharing in iChat. You can control your Mac from a Windows PC, or from an older version of Mac OS X as well! If you’ve already enabled Screen Sharing, follow these steps to enable any VNC connection:
Click the Sharing icon.
The Sharing Preferences dialog appears.
Click the Screen Sharing entry.
Screen sharing is enabled.
Click the Computer Settings button.
You refine your sharing settings here.
Click the VNC Viewers May Control Screen with Password check box to select it.
This enables VNC viewers to access your screen.
Click within the password text box and enter a password for VNC applications.
Make doggone sure that you set up the password access correctly for VNC or don’t run it! A hacker could have free remote control over your Mac OS X Desktop.
Click OK to exit the Computer Settings sheet, and close the System Preferences window.
Your changes are saved.
