Just hours after releasing version 1.1 of Take Control of Upgrading to High Sierra today, I learned about a few last-minute issues, not the least of which was that Apple had changed the minimum system requirements for installing High Sierra and I hadn’t noticed before version 1.1’s publication. (It was OS X 10.7.5, but now it’s 10.8.) A few other small things cropped up too, enough that I decided to push out a quick version 1.1.1 to address these small issues.
If you already downloaded version 1.1, you can grab version 1.1.1 from your Take Control Library.
