Take Control of Screen Sharing in Lion
Control one Mac from another, or from a iPad, iPhone, or iPod touch!
Screen sharing gives you the power to control the mouse and keyboard of one Mac while you sit at another, whether it's just across the room or on the other side of the world. It's great for helping far-flung colleagues and relatives run their Macs, managing a remote server, and collaborating in real time on documents.
In recent versions of Mac OS X, Apple has piled on the options, enabling screen sharing via iChat, Bonjour, directly by entering an IP address, and Back to My Mac. Plus, Skype can do screen sharing with Macs and Windows computers, and various iOS apps let you run your Mac by tapping and dragging.
Join networking guru Glenn Fleishman as he helps you identify the best screen-sharing option for your needs. You'll learn how to set up screen sharing, get tips on using iChat and Apple's Screen Sharing application, and find directions for Skype screen sharing. A separate chapter explains how to use the iTeleport and LogMeIn apps on your iPad, iPhone, or iPod touch to run a Mac remotely.

Read Me First
This book will help you master sharing a remote computer screen from Mac OS X 10.7 Lion (with details for 10.6 Snow Leopard and 10.5 Leopard) and teach you how to get a reliable connection with the greatest versatility. It also explains the use of an iPhone, iPad, or iPod touch for remote access to a screen. It was written by Glenn Fleishman and edited by Tonya Engst (with Dan Frakes as technical advisor), and published by TidBITS Publishing Inc.

Introduction
Over 20 years ago, working from my desktop computer, I manipulated and saw the screen of a system that was in a server room. It was magical. I could work with the server just as if I were sitting in front of it, using its programs and moving objects on its desktop—via a 2,400 bps modem!
That sense of wonder still pervades me when I use screen sharing today. Instead of using dial-up software, or even a 10 Mbps (fast!) local Ethernet network, I use broadband feeds over the Internet to reach computers across town or 3,000 miles away.
Screen sharing, the general name for this technology, gives you access to applications and data stored on another computer, even though your keyboard and mouse aren’t connected to that computer. It lets you see a remote computer screen in real time, and it may also allow you to control the remote computer.
In Mac OS X 10.4 Tiger and earlier versions of Mac OS X, screen sharing was something you had to install or spend significant time figuring out how to use. Apple made screen sharing part of the system, available on tap, in 10.5 Leopard. Improvements appeared in 10.6 Snow Leopard, and the technology reached a new level of utility in 10.7 Lion.
In Lion, screen sharing comes in several forms, and in this book I explain how to use each of them. In some cases, you must have an account and a password on the machine you want to access remotely. However, one particular method—screen sharing over iChat—requires just a buddy who gives you permission, at the time of access, to view or control his or her screen.
I also explain how to use screen sharing via Skype, and the role of Back to My Mac with screen sharing.
Quick Start to Screen Sharing
To learn how to set up your Macintosh or iOS device to view or control the screen of another computer, you’ll benefit from reading Learn the Basics of Screen Sharing carefully, in order to best match your situation to your needs. After that, focus on the material that describes the type—or types—of screen sharing that you want to do. However, if you have specific questions, each chapter also stands on its own.
I start by explaining how screen sharing works, then provide details on Lion’s Screen Sharing app, which is used by all of Lion’s options for remote access, whether via iChat, Back to My Mac, or Bonjour. Skype is covered separately. A chapter about troubleshooting connections comes at the end.
Learn background info to configure like a pro:
- To quickly find out about what’s different with screen sharing in Lion, read What’s New in Lion, a page or so ahead.
- Discover the many Uses of Screen Sharing.
- Determine the screen-sharing technique that best matches your situation in Options for Screen Sharing, and get details and reassurance in Security behind Screen Sharing.
For iChat:
- Set up ad hoc screen sharing with Share via iChat. You can share media or give a presentation with Use iChat Theater.
For other forms of built-in Mac OS X screen sharing:
- Get started with the directions for how to Set Up Screen Sharing.
- Get a handle on how to Use the Screen Sharing Application.
- Make a screen-sharing connection: read Share via Bonjour, Share via a Direct Network Connection, or Share via Back to My Mac.
For third-party and other ways to share a screen:
- Use Skype to share your screen with another Skype user, allowing remote viewing but not control, all for free. See Share via Skype.
- Turn your iPhone, iPod touch, or iPad into a remote-control appliance using one of several software packages. See Sharing Screens in iOS.
Solve problems:
- Find answers to common problems in:
- iChat Connection Problems
- Bonjour and Direct Connection Problems
- Back to My Mac Connection Problems
- Solve problems that come up if a Firewall Blocks Access or that relate to waking a sleeping computer (see Solving Sleep).

What's New in This Edition
This edition of my Take Control of Screen Sharing... ebook still talks about sharing screens in Mac OS X 10.5 Leopard and 10.6 Snow Leopard, but it’s more keenly focused on 10.7 Lion and the introduction of Apple’s iCloud online service, which has replaced Apple’s MobileMe service.
Highlights of the most important changes in this edition include:
- I’ve added new information about screen sharing in Lion. For an overview, read What’s New in Lion, a few pages ahead.
- Share via Back to My Mac now talks about using Back to My Mac with iCloud, instead of with MobileMe as it did previously. Also, for simplicity’s sake, this book has incorporated all the relevant parts of the formerly separate Take Control of Back to My Mac. (You may download the Snow Leopard version of that ebook at no charge—see Ebook Extras.)
- Share via Skype has been updated to cover version 5, a major revision to the software that has removed some screen-sharing features.
- I removed most of the information about VNC (Virtual Network Computer) technology as it is no longer required as an alternative to far simpler and more powerful choices.
- I deleted the appendix about port mapping because the screen-sharing technology discussed in this book no longer requires such a complicated setup.
- Because the Take Control series has begun producing EPUBs in-house, the EPUB version of this edition has an improved layout and looks more like a Take Control ebook.

What versions of Mac OS X does this ebook cover?
This ebook covers Mac OS X 10.7 Lion, but it also brings 10.6 Snow Leopard and 10.5 Leopard along for the ride. We previously sold a Leopard and then a Snow Leopard edition of this ebook, but because the details about services like Back to My Mac and Skype have changed a great deal over the years, we no longer sell or update those older editions. Instead, everyone running 10.5 Leopard or later should use this Lion edition.
Can I read this ebook on an iPad, iPhone, iPod touch, or Kindle?

On page 61 and 66 of Take Control of Screen Sharing in Lion, Glenn wrote that you can't use an iCloud account to access an AirPort Disk or Time Capsule via Back to My Mac, even though you can with a MobileMe account. As Glenn had suspected when he drafted the manuscript, Apple has now added iCloud-based access to Time Capsule drives and USB-attached AirPort drives. Of course, accessing those drives just lets you work with the files on those drives—there is no screen to share on a Time Capsule or AirPort base station! Glenn wrote much more about this topic in his TidBITS article, AirPort Utility 6.0 Adds iCloud Support but Removes Many Features.
