Apple desktop came all the way cross country and looks brand new!  Thought it would have high sierra, but it had the latest operating system, Mojave.  It did come with a plug in keyboard & mouse so I bought a wireless mouse.For a guy that always had PC's there is a learning curve, but downloading my Google browser that I used before, has made the transition much easier.  The 21 inch screen is so bright and the machine is soo fast compared to what I was use to.  The biggest adjustment is having to enter all these crazy passwords.  Apple requires more complicated passwords than I have ever seen.  I give this supplier 5 stars!
