Thanks for your quick reply John. I should have been more specific. We access our customer's screens to help them setup software, solve problems, etc. While we can use screen sharing this way, it requires a lot of setting changes and configurations on the other person's computer - more than many of the novices can handle. In the past we could just have them Launch iChat and we could request to Share Their Screen. We don't see this function in Facetime. Is there still this simple option in any of the Mavericks' software? If not, do you know of any Shareware than brings the iChat like screen sharing to Mavericks? Thanks!
