Immediately it was malfunctioning in the Music app. Then my Zoom apps would not function properly. Then my gaming apps regularly froze and created spectacular bizarre images on my screen that I could only hard-crash my way out of.  I spent 45 minutes with Amazon support first, then 45 minutes with Apple support for the Music problem. Then a series of awkward phone appointments with Apple most of which resulted in getting a call and having no message until the voice said: "We're sorry you have not responded. You will have to reschedule."  This after I was screaming and yelling and ultimately pushing buttons trying on the third and fourth times to get a response.  Then I got a time set up when Apple would call ME.  They never called.  Then I called again and spent an hour with the very nice and patient Apple technician, but ultimately it did not resolve the problem.  Throughout all of this were were multiple reloads, restarts, reboots, re-imaging, re-stripping, all of which would take up to three hours at a time.  And still it does not work.. NOW I am not seeing a "return" option here, after $3,000 and a badly functioning machine. I'm furious and don't even know where to go next.Addendum: Amazon was very helpful in arranging for me to return my computer. I had saved the boxing materials, packed it all up, printed the special label they e-mailed me, and delivered it safely to UPS. Amazon made returning it blessedly NOT painful.
