Screen sharing in OSX Mountain Lion Fix

After upgrading to Apple OSX Mountain Lion, I found that I was unable to connect to the upgraded mac via Screen Sharing any more.

After searching in vain for solutions, in desperation I decided to play with the screen sharing settings in case there was a new option or something.

In the end I was able to get it working again like so:

  1. Open the ‘Computer Settings’ option (System Preferences > Sharing > Screen Sharing)
  2. Change the ‘Anyone May request permission to control screen’ and Save.
  3. Open the ‘Computer Settings’ again and return the setting to it’s original state and Save again.
  4. Stop and start Screen Sharing in the Sharing Screen

It seems that the upgrade may have left the screen sharing settings in an unusable state, and simply re-saving the settings as above was enough to kick it into life again.

Your mileage may vary – but hope putting this ‘out there’ is useful to you too.
