I'm not new to Mac's. I've had nearly every model of iPhone, at least three MacBook pro's, multiple iPads, and I have two other iMacs. This one was bought for my office. It is painfully slow. Slower than my 2012 iMac. It is so slow it is almost not useable, I'm not sure how long I will be able to stand it. My intention was to not have to take my MacBook to the office everyday, but that didn't work!
