I do a lot of family IT for macOS in Tauranga and over to Cambridge, which I not mind travelling to, for elderly relatives. But I have a 74yr friend on the Nth Shore who rings me every so often for some help. Trying to rectify things over the phone is becoming a bit of a hassle as he tends to forget terms like; Dock, Menu bar & Tab bar etc, return key or left click on OK etc, which is all a bit tiresome 😞.

Now I know that macOS Messages has 'Ask to Share Screen' and there is also an inbuilt 'Screen Sharing.app', I have never used these macOS services but I believe using them would lower my stress levels during these help sessions. 😀

I obviously do not want to pay money for this ability. So has anyone had experience screen sharing on macOS and is it easy to take control of the other persons machine to rectify any issues and to educate. 

Thanks
