What is the difference between enabling remote management and enabling screen sharing?
Apple's support article, http://support.apple.com/kb/HT4715, says:
If the Apple Remote Desktop administrator authenticates with a name that is different from the user logged on at the remote computer, the following applies:
- If the service was enabled by turning on Screen Sharing, the screen sharing user is presented with the option to request sharing access from the user logged on at the display.
- If the service was enabled by turning on Remote Management, the screen sharing user can simply choose to share the display.
- The screen sharing user can always choose to log in to their own session.
It also states:
If the remote computer's display is at the login window, the Apple Remote Desktop administrator will simply share the display. This is equivalent to how screen sharing works in earlier versions of Mac OS X.
A third party VNC viewer will always be connected to the login window. If the login window is not on the display, a new login window is started that is not shown on the display. The screen sharing user can then log in with any valid account on that computer.
So, I presume that it is using the same protocol (VNC) underneath and just behaves a little different depending on which option you enable.
What is Apple's remote client? Is it the Screen Sharing app in CoreServices (/System/Library/CoreServices/Screen Sharing.app) or is there something else I might have missed?
Lastly, what is the Mac App Store "Apple Remote Desktop" product ($80, http://itunes.apple.com/us/app/apple-remote-desktop/id409907375?mt=12) and how does it differ from the above?
