Hi Tard1s40,


In my experience, the "Preparing" stage on non-SSD Macs takes longer than 15 minutes.


On one of my older Macs (1TB 5400rpm HDD), it took around 45 minutes to prepare. Be patient. If it still does not go, restart your Mac, then try in Safe Mode: Start up your Mac in safe mode - Apple Support.


Cheers,


Jack
