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:
- Open the ‘Computer Settings’ option (System Preferences > Sharing > Screen Sharing)
- Change the ‘Anyone May request permission to control screen’ and Save.
- Open the ‘Computer Settings’ again and return the setting to it’s original state and Save again.
- 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.
