We just got a refurbished iMac, and there are a bunch of set up screens that seem to be impossible to navigate through. I have an older iMac, so am not totally ignorant, but am stuck at square #1 with this thing! I expected it to just come on...
I know what you describe is the logical way to do it, but in this case the "enter" key does not advance the screen. Tabbing moves the highlighted boxes, but enter doesn't select them.
After "escape" to voice-over explanations and back to setup I got past the country screen, but the next, select a keyboard does the same thing. Choose "United States" but enter doesn't advance and tabbing to the "continue" button doesn't either.
It is a wireless keyboard and mouse.
