Setting up new Mac mini

It clearly shows on the screen after the first bootup that you should turn on the wireless keyboard and mouse, but it doesn't work. Thankfully I had an old mac keyboard and mouse handy and used them for the intial start, then I could pair my wireless keyboard and mouse. It should work with wireless as well!

You need a wired keyboard and mouse to get up and going then you can pair the bluetooth hardware later. Wired hardware works 100% of the time. Try again.
