I’m not sure how to reach out to you any other way, so thought I’d try through this post. I have an iMAC 20 that I bought from a friends friend, friend. Anyway, it was working fine but because of the Administrator and password lock, I couldn’t download anything. I bought the Windows 10 download cheaply through my company and wanted to download it, so I followed the instructions and was happy to see it working. I went through the “flying” welcome screen, the posting of new information, my address, my shortname, my password, reconfirming password, where I was using the computer, etc. Hit enter, looks like it’s processing the information, but within 30 seconds puts me back into the “flying” welcome screen and asking me about logging in as a new user again. Obviously some type of glitch. I’ve been scouring the web trying to find out what might be happening and a possible fix, to no avail. Any suggestions besides bringing it in to someone? Thank you for any direction you can offer.
