Hello Everyone, You know, I almost hesitate to post the following supposition for fear of unleashing a firestorm of debate but after my recent experiences updating several Macs from Yosemite to El Capitan, I am compelled to proceed.
For the life of me, I cannot fathom why some who upgrade from Yosemite to El Capitan do so with virtually no negative results while others, experience countless and, according to them, almost catastrophic consequences, from an accessibility perspective. I have long suspected the following supposition but have recently begun to test my hypothesis, said hypothesis being the following: During the upgrade process, using VoiceOver too soon, can interrupt the installation and that it is this interruption that leads to the increase in the number of VoiceOver accessibility problems. Scenario: A totally blind person begins the upgrade process or even performs a fresh install of El Capitan. During this process, several screens are displayed but near the very end of the process, VoiceOver can be used even though the installation is not yet complete. Visually, the screen may display something like Completing Update. This screen is not comfortably accessible and, as a result, the totally blind person may not realize that there is still a progress bar that has not yet reached 100%. As a result of this lack of knowledge, the user begins performing VoiceOver actions including switching screen focus, etc. When this happens, I believe that the extremely final installation tasks are not properly completed. Whenever I install a copy of the OS, I am very careful to allow the installation process to complete and, sometimes, that final screen can remain on the display for what appears to be a remarkably long time, relative to the entire installation process. During my testing, in each instance in which I did not wait for the screen to disappear or I began using VoiceOver to interact with the OS before the screen disappeared, I noticed a significant degradation in the performance of VoiceOver. Now again, let me emphasize that this is just a guess on my part and in no way do I hold that it is a correct one. Be that as it may, I suggest that this is something to consider when updating your Mac. Mark -- The following information is important for all members of the Mac Visionaries list.
