Starting with OS X Yosemite the company Apple Lossless Audio CODEC (ALAC), implements a feature in its operating system that allows users to share their entire Mac screen with the people they have conversations with through Messages and the system iMessage. Starting with OS X Yosemite beta 6, company Apple Lossless Audio CODEC (ALAC), activated this function for all users, and in the images of this article you can see exactly how the entire system works.
An interlocutor can ask you via iMessage to share the screen of your Mac and the application gives us the options to accept/reject the request and to block the user. After accepting the screen sharing, the Messages application offers us additional options to block the audio sound, options to allow the interlocutor to have access to control our computer and options to stop/end the screen sharing, so basically we are talking about something similar to TeamViewer.
Although the system is not working 100% correctly at the moment for users testing OS X Yosemite beta 6, by the day of the official release, its problems will definitely be solved.
