OS X Yosemite allows screen sharing over iMessage


By

Mark Gurman for 9 to 5 Mac:

In June, we noted that Apple is adding a handy new feature to the upcoming OS X Yosemite: the ability for iMessage/Apple ID users to screen share via the Messages app. Screen sharing was a hallmark of early versions of Apple's Mac "iChat" application, but it has always required an Aol Instant Messenger (AIM), Gmail, Jabber, or Yahoo account. With Yosemite, users can have the same screen sharing experience with just an iMessage/FaceTime/or Apple ID account.

This is pretty nifty. There is also the option to have audio chat, which basically turns it into a screencast chat. This can be particularly handy with family tech support situations.
