I recently obtained a 15 inch macbook pro retina machine circle 2012, running Catalina. the software upgraded to 10.15.7
However, I am rather new to the voiceover keystrokes, finding the user guide incorporated into the system, not fully readable from my main computer using my other screen reader. I am wanting to get the last fully available user guide for voiceover, with keystrokes close to Catalina, so I can read and practice until I feel more comfortable.
I am guessing that would be either sierra or perhaps High Sierra, although apple support tells me it was more of a mid point upgrade than a major new OS.Again I prefer reading, not a video or podcast.Any idea where to find this guide?
