Hello Brian, I am so sorry that your experience has been this difficult.
To be honest, I wanted to caution you about how to install Yosemite after having first upgraded to El Capitan. I did not, given that you were already on your proverbial way, as it were. I was hoping that all would be well but since it clearly is not, I will now post my recommendation. When I learned that you were attempting to roll back to Yosemite, I wanted to caution you that merely installing Yosemite, even after erasing your disk may not be completely successful. The only way, in my opinion, to get a truly clean install is to delete the entire partition of the internal drive before installing an OS. While I am not making any excuses for your experience, the truth of the matter is that your project is not as simple as it would appear. Therefore, you should not be too hard on yourself or on the operating system. Things work the way they work and it takes time to understand how it's all put together. The truth of the matter is that Apple provides the only OS, of which I am aware, in which we, blind and low vision, can be truly self supporting. That does not mean, however, that there is no learning curve. Having said all of this, were you to have asked before undertaking this project I would have recommended that you first learn how to use the Startup disk option located in the System Preferences area. Then I would have suggested that you explore the Disk Utilities application in order to familiarize yourself with its layout and how VoiceOver interacts with it. I would have advised you to attach a drive or two, to your Mac and practice formatting, partitioning and re-partitioning the practice drive. These skills are important, especially when dealing with a primary disk partition on an internal drive. Then, and only then, would I have recommended that you perform a complete fresh install after first having deleted the partition of the internal drive. As it stands, I hope you will not give up on this project as, like it or not, it is an excellent learning opportunity. In short, just try again. Keep trying until you get it right. When I was learning how to do these things, sometimes, I had to make the attempt as many as three times before I was successful. Each time through, however, I learned something new about both the OS and, more importantly, about myself. One more thing, just as a side note, what I and many others do is to install a program like Super Duper in order to clone the internal drive to an external one, before upgrading to a new OS. Then, should we decide to rollback, as it were, we only need to copy the cloned copy from the external drive back to the internal one. The cloned drive is also bootable. Hang in there and know that we're all here, ready to assist.

My computer is now utterly useless as VO will read for a few seconds then stop for 3 to 5 minutes then read for a few seconds and stop again making the computer a giant freaking paperweight. The funniest thing about all this is I am supposed to be at an expo tomorrow talking up Apple to blind people, well F that. I could never recommend Apple to someone after this experience.Not sure how having nothing on the computer could cause so many issues but I would have taken the crappy Crapitan to this as Crapitan was useable in places just not safari, this is now a pile of junk. Will call Apple accessibility what a joke not sure how I have been the lucky one to have the worlds worst experience doing a clean install. -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
