I was trying to update from mac OS 10.13.6 to mac OS 10.14. I got pass the agreement thing that they showed me. I even clicked on installed. After that, I sort of get stuck. This is for one simple reason. At this stage, VoiceOver tells me that security agent has no windows. Thinking about maybe turning off apple script for VO, I went into the VO settings and unchecked the correct check box, but I run into the same problem. Now when I command- tab away and back to the same window, I get the busy message. Is there anything I need to check into to saulve this? What am I missing?
