With Apple's useful yet funky Back to My Mac feature, MobileMe users can share files and screens among their Macs, making it possible to grab a forgotten document or even use a work machine from home or while on the road. It sounds great, but some people have required extensive assistance to get their routers working right, or have questions about security or about extended features like remote access to drives attached to an AirPort Extreme Base Station or Time Capsule. To that end, we've just released the version 1.2 update to Glenn Fleishman's Take Control of Back to My Mac.

This book is also available in a bundle with Glenn's just-published Take Control of Screen Sharing in Snow Leopard, which looks at the broad array of screen sharing options in both Mac OS X 10.5 Leopard and 10.6 Snow Leopard. It covers Back to My Mac briefly, but looks more completely at connections via iChat, Bonjour, direct IP addressing, and third-party possibilities such as Skype and iPhone apps. Look for a $5 discount bundle in the left margin of the Web page for either book.

(If you already own Take Control of Back to My Mac, note that this is a free update; to get your update, open your existing PDF to page 1 and then click Check for Updates. If you own the Leopard edition of Glenn's "Screen Sharing" ebook, look on its Check for Updates page for an upgrade discount, or look in your email for an update-related message.)
