This is my seventh Mac.  I wanted something with a newer OS so that I could download a newer version of Apple Pages for a project I am doing.  The retina screen is beautiful and, after a few snags, I was able to download Sonoma to replace the Big Sur that was on the computer.  It did not come with Mac keyboard or mouse.  The mouse works fine, but I swapped keyboards with my oldest Mac so that I have a Mac keyboard on the computer I will now be using most of the time.  I downloaded Pages.  Pages has been working perfectly and I am almost done laying out a 300 page book.  Have had no problems opening older versions and I can still save in Pages 09 if I want to open on my oldest Mac.  My only complaint is that the computer is very slow at certain things, mostly getting online and doing certain internet stuff.  I hope that problem can be fixed.  I love Macs and now have four in operation.  I bought the others new, but so far getting a used one at more than half the price seems to be working out for what I want to do.
