I don't like it because when I tried to download my Garmin GPS so I can keep my maps updated, it could not be completed.  I need that because I'm a over the road truck driver.  GPS helps me do my job.  I even took it to the Best Buy geek squad and they said it was a 2015 model and could not be updated.  He told me that apple sells the older laptops and you can't download things with it crashing the whole system.  If I'd known that I would not have bought a 2015 used laptop.  So it was a waste of money for me.  Live and learn.
