I just bought my first ever mac - mac mini - and now I'm trying to get it running. I have connected it to a dell monitor through hdmi and a windows usb keyboard so far.
When I power it on I get the screen with the apple and a progress bar. Once this progress bar is done, the screen turns sort of dark gray for like 10 seconds and then 2 images are displayed (one at a time). They both seem to indicate that I need to turn on/off some switch but there are no switches on my mac mini it seems?! I have network cable plugged in in case that is any help. Check out the images here:
