I bought this imac 4 months ago.  Pretty good price.  I'm into month 4 of purchase and this thing is all over the map.  It's enlarged itself and I have to scroll manually from side to side to even read anything.  I'm really disappointed with the performance and the awful look of the screen, plus all the time I spend scrolling from side to side just to be able to get any work done.Also, while reading my email on protonmail, the entire top of the screen has a complete line of strange icons that appear to be like little purple blocks.I've bought several refurbs in the past few years and have had good experiences but  not wiith this one.
