"Take Control of Upgrading to Tiger" Updated to Version 1.0.1 -- When we released the 1.0 version of this ebook simultaneously with Apple's release of Tiger, we knew that we'd be doing a fast update - important new information always comes to light during the first few days after the release of a major operating system. The new version, now based on 44 test installations of Tiger, walks readers through installing Mac OS X like never before.
