Doing more with Messages
Last week we wandered about Mountain Lion’s Messages application to get a feel for the territory. In today’s lesson we’ll dig into some of Messages’ less obvious features, including screen sharing, initiating remote slideshows and presentations, and viewing past chats.
Messages and screen sharing
When exploring the Mac’s sharing features I explained how to share the screen of another Mac on your local network. Through Messages it’s possible to do the same thing, but over the Internet.
To do this, each participant must use an AIM, Bonjour, Google Talk, or Jabber account. Screen sharing isn’t available through the iMessage protocol (meaning two iCloud accounts) or Yahoo.
To share someone’s screen, select their name in your buddy list and from the Buddies menu choose Ask to Share PersonX’s Screen (where PersonX is the person you want to interact with). That person will receive an invitation via an alert sound and a dialog box. For them to allow their screen to be shared, they simply click the dialog box. They can also elect to send you a text reply. For example, if they are in the middle of something, they can just click the Text Reply button and type I can’t right this second. Try again in 5 minutes.
